130-456: The Savage Striker was a bolt action pistol produced from 1999 to 2005 by Savage Arms for metallic silhouette shooting and hunting . The pistol was based on the action of the Savage Model 110 and was sold with a composite stock, originally with a center grip, but later also with a rear grip as an alternative. The pistol was designed for right handed shooters, and had a loading port on
260-414: A competitive Olympic sport prior to World War I . For smoothbore weapons such as shotguns, small metallic balls known as shots are typically used, which is usually contained inside a semi-flexible, cup-like sabot called " wadding ". When fired, the wadding is launched from the gun as a payload-carrying projectile, loosens and opens itself up after exiting the barrel, and then inertially releases
390-420: A metallic , paper , or plastic case that is precisely made to fit within the barrel chamber of a breechloading gun, for convenient transportation and handling during shooting. Although in popular usage the term "bullet" is often used to refer to a complete cartridge, the correct usage only refers to the projectile. Cartridges can be categorized by the type of primer. This can be accomplished by igniting
520-460: A spring -loaded hammer to strike a percussion cap placed over a conical "nipple", which served as both an " anvil " against the hammer strike and a transfer port for the sparks created by crushing the cap, and was easier and quicker to load, more resilient to weather conditions, and more reliable than the preceding flintlocks. Modern primers are basically improved percussion caps with shock-sensitive chemicals (e.g. lead styphnate ) enclosed in
650-460: A "cock on open" system. Although this bolt system has been rarely used in commercial sporting rifles (the Vostok brand target rifles being the most recognized) and has never been exported outside of Russia, although large numbers of military surplus Mosin–Nagant rifles have been sporterized for use as hunting rifles in the following years since the end of World War II. The Swing was developed in 1970 in
780-446: A 250 mm barrel (10 inches) and a weight of 1814 grams (4 pound). It was delivered with a mount for attaching a scope sight and ambidextrous grip. The model 510/516 Striker was produced from 1998 to 2005. It had a stainless finish with a left handed charging handle and right hand ejection. It chambered for .223 Rem , .22-250 Rem , .243 Win , 7mm-08 Rem , .260 Rem , and .308 Win with two or three round magazines. Its total length
910-546: A bolt-action shotgun, albeit one designed to be attached to an M16 rifle or M4 carbine using an underbarrel mount (although with the standalone kit, the MASS can become a standalone weapon). Mossberg 12-gauge bolt-action shotguns were briefly popular in Australia after the 1997 changes to firearms laws , but the shotguns themselves were awkward to operate and had only a three-round magazine, thus offering no practical or real advantages over
1040-465: A brass case can be work-hardened to withstand the high pressures, and allow for manipulation via extraction and ejection without rupturing. The neck and body portion of a brass case is easily annealed to make the case ductile enough to allow reshaping so that it can be handloaded many times, and fire forming can help accurize the shooting. Steel casing is used in some plinking ammunition, as well as in some military training ammunition (mostly from
1170-604: A brass pin projecting from the side and struck by the hammer. This pin also afforded the means of extracting the cartridge case. This cartridge was introduced in England by Lang, of Cockspur Street, London, about 1845. In the American Civil War (1861–1865) a breech-loading rifle, the Sharps , was introduced and produced in large numbers. It could be loaded with either a ball or a paper cartridge . After that war, many were converted to
1300-475: A bullet attached to the top. Flobert then made what he called " parlor guns " for this cartridge, as these rifles and pistols were designed to be shot in indoor shooting parlors in large homes. These 6mm Flobert cartridges do not contain any powder. The only propellant substance contained in the cartridge is the percussion cap. In English-speaking countries, the 6mm Flobert cartridge corresponds to .22 BB Cap and .22 CB Cap ammunition. These cartridges have
1430-479: A bullet in a paper cartridge. Thick paper is still known as " cartridge paper " from its use in these cartridges. Another source states the cartridge appeared in 1590. King Gustavus Adolphus of Sweden had his troops use cartridges in the 1600s. The paper formed a cylinder with twisted ends; the ball was at one end, and the measured powder filled the rest. This cartridge was used with muzzle-loading military firearms, probably more often than for sporting shooting,

#17328686314461560-419: A confined space—such as the cartridge casing (reinforced by the chamber wall) occluded from the front by the projectile (bullet, or wadding containing shots / slug ) and from behind by the primer (supported by the bolt / breechblock ). When the pressure builds up high enough to overcome the crimp friction between the projectile and the case, the projectile separates from the case and gets propelled down
1690-418: A container for the propellant powders and also serves as a protective shell against the elements; it attaches the projectile either at the front end of the cartridge ( bullets for pistols , submachine guns , rifles , and machine guns ) or inside of the cartridge ( wadding / sabot containing either a quantity of shot (pellets) or an individual slug for shotguns ), and align it with the barrel bore to
1820-410: A conventional double-barreled shotgun. Some pistols use a bolt-action system, although this is uncommon, and such examples are typically specialized hunting and target handguns. Most of the bolt-action designs use a rotating bolt (or "turn pull") design, which involves the shooter doing an upward "rotating" movement of the handle to unlock the bolt from the breech and cock the firing pin , followed by
1950-469: A firing mechanism without a hammer , but there are some hammer-fired models, such as the Merkel Helix. Firearms using a hammer usually have a comparably longer lock time than hammerless mechanisms. In the sport of biathlon , because shooting speed is an important performance factor and semi-automatic guns are illegal for race use, straight pull actions are quite common and are used almost exclusively in
2080-401: A firing, the round is first inserted into a "ready" position within the chamber aligned with the bore axis (i.e. "in battery "). While in the chamber, the cartridge case obturates all other directions except the bore to the front, reinforced by a breechblock or a locked bolt from behind, designating the forward direction as the path of least resistance . When the trigger is pulled,
2210-580: A gravity-operated tubular magazine in the stock. Another more well-known bolt-action repeating rifle was the Vetterli rifle of 1867 and the first bolt-action repeating rifle to use centerfire cartridges was the weapon designed by the Viennese gunsmith Ferdinand Fruwirth in 1871. Ultimately, the military turned to bolt-action rifles using a box magazine ; the first of its kind was the M1885 Remington–Lee , but
2340-666: A license for his patent, and this is how the S&;W Model 1 saw the light of day in 1857. The patent didn't definitely expire until 1870, allowing Smith & Wesson competitors to design and commercialize their own revolving breech-loaders using metallic cartridges. Famous models of that time are the Colt Open Top (1871–1872) and Single Action Army "Peacemaker" (1873). But in rifles, the lever-action mechanism patents were not obstructed by Rollin White's patent infringement because White only held
2470-547: A metallic cartridge's powder charge – were invented in the 1860s as well, the Berdan and the Boxer systems. The United States purchased 900 Greene rifles (an under hammer, percussion capped, single-shot bolt-action that used paper cartridges and an ogival bore rifling system) in 1857, which saw service at the Battle of Antietam in 1862, during the American Civil War ; however, this weapon
2600-403: A mixture of highly energetic gases and generates a very high pressure inside the case, often fire-forming it against the chamber wall. When the pressure builds up sufficiently to overcome the fastening friction between the projectile (e.g. bullet) and the case neck, the projectile will detach from the case and, pushed by the expanding high-pressure gases behind it, move down the bore and out
2730-426: A modern gun must not only load and fire the piece but also provide a method of removing the spent case, which might require just as many added moving parts. Many malfunctions occur during this process, either through a failure to extract a case properly from the chamber or by allowing the extracted case to jam the action. Nineteenth-century inventors were reluctant to accept this added complication and experimented with

Military and commercial producers continue to pursue the goal of caseless ammunition . Some artillery ammunition uses the same cartridge concept as found in small arms . In other cases, the artillery shell is separate from the propellant charge. A cartridge without
2990-601: A patent concerning drilled cylinders and revolving mechanisms. Thus, larger caliber rimfire cartridges were soon introduced after 1857, when the Smith & Wesson .22 Short ammunition was introduced for the first time. Some of these rifle cartridges were used in the American Civil War, including the .44 Henry and 56-56 Spencer (both in 1860). However, the large rimfire cartridges were soon replaced by centerfire cartridges, which could safely handle higher pressures. In 1867,
3120-416: A projectile is called a blank ; one that is completely inert (contains no active primer and no propellant) is called a dummy ; one that failed to ignite and shoot off the projectile is called a dud ; and one that ignited but failed to sufficiently push the projectile out of the barrel is called a squib . The cartridge was invented specifically for breechloading firearms. Prior to its invention,
3250-583: A rearward "pull" to open the breech, extract the spent cartridge case, then reverse the whole process to chamber the next cartridge and relock the breech. There are four major turn bolt-action designs: the Remington M-700 , possibly the single most numerous produced rifle in history which is now also used as basis for most custom competition rifle actions, along with the Mauser system, the Lee–Enfield system, and
3380-596: A relatively low muzzle velocity of around 700 ft/s (210 m/s). French gunsmith Benjamin Houllier improved the Lefaucheux pinfire cardboard cartridge and patented in Paris in 1846, the first fully metallic pinfire cartridge containing powder in a metallic cartridge. He also included in his patent claims rim and centerfire primed cartridges using brass or copper casings. Houllier commercialised his weapons in association with
3510-449: A rod to optimize the gas seal , and are thus clumsy and inconvenient, severely restricting the practical rate of fire of the weapon, leaving the shooter vulnerable to the threat of close combat (particularly cavalry charges ) as well as complicating the logistics of ammunition. The primary purpose of using a cartridge is to offer a handy pre-assembled "all-in-one" package that is convenient to handle and transport, easily loaded into
3640-471: A rotating bolt design. Johann Nicholas von Dreyse 's rifle of 1838 was accepted into service by Prussia in 1841, which was in turn developed into the Prussian Model in 1849. The design was a single shot breech-loader and had the now familiar arm sticking out from the side of the bolt, to turn and open the chamber . The entire reloading sequence was a more complex procedure than later designs, however, as
3770-435: A round bullet and either brass or paper casing. The cartridge was loaded through the breech and fired with a needle. The needle-activated centerfire breech-loading gun would become a major feature of firearms thereafter. Pauly made an improved version, protected by a patent, on 29 September 1812. Probably no invention connected with firearms has wrought such changes in the principle of gun construction as those effected by
3900-505: A separate bolthead that rotates with the bolt and the bearing lugs, in contrast to the Mauser system where the bolthead is a non-removable part of the bolt. The Mosin–Nagant is also unlike the Lee–Enfield system where the bolthead remains stationary and the bolt body itself rotates. The Mosin–Nagant bolt is a somewhat complicated affair, but is extremely rugged and durable; like the Mauser, it uses
4030-427: A simple capsule, and the corresponding case has two small flash holes with a bulged bar in between, which serves as the "anvil" for the primer. Boxer primers, patented by Royal Artillery colonel Edward Mounier Boxer also in 1866, are more complex and have an internal tripedal "anvil" built into the primer itself, and the corresponding case has only a single large central flash hole. Commercially, Boxer primers dominate

4160-430: A single lethal shot from a safe distance. Target shooters favour single-shot bolt actions for their simplicity of design, reliability, and accuracy. Bolt-action shotguns are considered a rarity among modern firearms but were formerly a commonly used action for .410 entry-level shotguns, as well as for low-cost 12- gauge shotguns. The M26 Modular Accessory Shotgun System (MASS) is the most recent and advanced example of
4290-515: A small button-shaped capsule. In the early paper cartridges , invented not long after the percussion cap, the primer was located deep inside the cartridge just behind the bullet, requiring a very thin and elongated firing pin to pierce the paper casing. Such guns were known as needle guns , the most famous of which was decisive in the Prussian victory over the Austrians at Königgrätz in 1866. After
4420-408: A small charge of an impact -sensitive explosive compound or by an electric-sensitive chemical mixture that is located: at the center of the case head ( centerfire ); or inside the rim ( rimfire ); or inside the walls on the fold of the case base that is shaped like a cup (cupfire); or in a sideways projection that is shaped like a pin ( pinfire ) or a lip (lipfire); or in a small bulge shaped like
4550-495: A smaller hammer that had a hollow to fit on the nipple when released by the trigger. The shooter placed a percussion cap (now made of three parts of potassium chlorate , two of fulminate of mercury and powdered glass) on the nipple. The detonating cap thus invented and adopted brought about the invention of the modern cartridge case, and rendered possible the general adoption of the breech-loading principle for all varieties of rifles, shotguns, and pistols . This greatly streamlined
4680-413: A specific cartridge type is tightly controlled and few types are interchangeable in any way. Exceptions do exist but generally, these are only where a shorter cylindrical rimmed cartridge can be used in a longer chamber, (e.g., .22 Short in .22 Long Rifle chamber, .32 H&R Magnum in .327 Federal Magnum chamber, and .38 Special in a .357 Magnum chamber). Centerfire primer type (Boxer or Berdan, see below)
4810-529: A specific weapon's type of action. However, both straight pull and rotating bolt rifles are types of bolt-action rifles. Lever-action and pump-action weapons must still operate the bolt, but they are usually grouped separately from bolt-actions that are operated by a handle directly attached to a rotating bolt. Early bolt-action designs, such as the Dreyse needle gun and the Mauser Model 1871 , locked by dropping
4940-417: A squib load obstructing the barrel will generate dangerously high pressure, leading to a catastrophic failure and potentially causing severe injuries when the gun blows apart in the shooter's hands. Actor Brandon Lee 's infamous accidental death in 1993 was believed to be caused by an undetected squib that was dislodged and shot out by a blank . Beginning in the 1860s, early metallic cartridges (e. g. for

When the primer powder starts combusting, the flame is transferred through an internal touch hole called a flash hole to provide activation energy for the main powder charge in the barrel. The disadvantage Is that the flash pan cAN still be exposed to
5200-757: A trigger derived from the Finnish Mantari, the Swing was commercially successful, with the basic design reused in the Paramount, RPA Quadlock and Millenium rifles. The Vetterli rifle was the first bolt-action repeating rifle introduced by an army. It was used by the Swiss army from 1869 to circa 1890. Modified Vetterlis were also used by the Italian Army . Another notable design is the Norwegian Krag–Jørgensen , which

The first integrated cartridge was developed in Paris in 1808 by the Swiss gunsmith Jean Samuel Pauly in association with French gunsmith François Prélat . Pauly created the first fully self-contained cartridges: the cartridges incorporated a copper base with integrated mercury fulminate primer powder (the major innovation of Pauly),

5460-451: A wadding, as the wadding obturates the bore better and typically slides less frictionally within the barrel. When a propellant is ignited and begins to combust , the resulting chemical reaction releases the chemical energy stored within. At the same time, a significant amount of gaseous products are released, which are highly energetic due to the exothermic nature of the reaction. These combustion gases become highly pressurized in

Similarly, the use of the wrong type of cartridge in any given gun can damage the gun, or cause bodily injury. Cartridge specifications are determined by several standards organizations, including SAAMI in the United States, and C.I.P. in many European states. NATO also performs its own tests for military cartridges for its member nations; due to differences in testing methods, NATO cartridges ( headstamped with

A bullet can be made of virtually anything (see below ), but lead is the traditional material of choice because of its high density, malleability , ductility , and low cost of production . However, at speeds greater than 300 m/s (980 ft/s), pure lead will melt more and deposit fouling in rifled bores at an ever-increasing rate. Alloying
5850-841: Is that propellant gas can blow back past the neck and leak into the chamber. Constituents of these gases condense on the (relatively cold) chamber wall, and this solid propellant residue can make extraction of fired cases difficult. This is less of a problem for small arms of the former Warsaw Pact nations, which were designed with much looser chamber tolerances than NATO weapons. Aluminum-cased cartridges are available commercially. These are generally not reloaded, as aluminum fatigues easily during firing and resizing. Some calibers also have non-standard primer sizes to discourage reloaders from attempting to reuse these cases. Plastic cases are commonly used in shotgun shells , and some manufacturers offer polymer -cased centerfire pistol and rifle cartridges. As firearms are projectile weapons ,

This made it slower to reload than other designs which used stripper or en bloc clips. Another historically important bolt-action system was the Gras system, used on the French Mle 1874 Gras rifle , Mle 1886 Lebel rifle (which

The first bolt-action rifle was produced in 1824 by Johann Nikolaus von Dreyse , following work on breechloading rifles that dated to the 18th century. Von Dreyse would perfect his Nadelgewehr (Needle Rifle) by 1836, and it was adopted by

The Mauser system is stronger than that of the Lee–Enfield system, due to two locking lugs just behind the bolt head, which make it better able to handle higher-pressure cartridges (i.e. magnum cartridges ). The 9.3×64mm Brenneke and 8×68mm S magnum rifle cartridge "families" were designed for

Another solution is to encase a lead core within a thin exterior layer of harder metal (e.g. gilding metal , cupronickel , copper alloys or steel), known as a jacketing . In modern days, steel, bismuth , tungsten , and other exotic alloys are sometimes used to replace lead and prevent release of toxicity into

Anschütz ; Peter Fortner junior designed the "Fortner Action", which was incorporated into the Anschütz 1827 Fortner . The Fortner action is specifically the straight-pull ball bearing lock action, which features spring-loaded ball bearings on the side of the bolt which lock into a groove inside

All four differ in the way the bolt fits into the receiver, how the bolt rotates as it is being operated, the number of locking lugs holding the bolt in place as the gun is fired, and whether the action is cocked on the opening of the bolt (as in both the Mauser system and the Mosin Nagant system) or the closing of the bolt (as in the Lee–Enfield system). The vast majority of modern bolt-action rifles were made for

In 1850 a metallic centerfire bolt-action breechloader was patented by Béatus Beringer. In 1852 another metallic centerfire bolt-action breechloader was patented by Joseph Needham and improved upon in 1862 with another patent. Two different systems for primers –the mechanism to ignite

In the earliest black powder muzzleloaders , a fuse was used to direct a small flame through a touch hole into the barrel, which was slow and subjected to disturbance from environmental conditions. The next evolution was to have a small separate charge of finer gunpowder poured into a flash pan , where it could start a "priming" ignition by an external source, when ignited

In 1993, the German Blaser company introduced the Blaser R93 , a new straight pull action where locking is achieved by a series of concentric "claws" that protrude/retract from the bolthead, a design that is referred to as Radialbundverschluss ("radial connection"). As of 2017 the Rifle Shooter magazine listed its successor Blaser R8 as one of the three most popular straight pull rifles together with Merkel Helix and Browning Maral. Some other notable modern straight pull rifles are made by Beretta , C.G. Haenel , Chapuis , Heym , Lynx , Rößler , Savage Arms , Strasser, and Steel Action. Most straight bolt rifles have

This invention has completely revolutionized the art of gun making, has been successfully applied to all descriptions of firearms and has produced a new and important industry: that of cartridge manufacture. Its essential feature is preventing gas from escaping the breech when the gun is fired, by means of an expansive cartridge case containing its own means of ignition.

The ability of the bolt to flex between the lugs and chamber, which also keeps the shooter safer in case of a catastrophic chamber overpressure failure. The disadvantage of the rearward-located bolt lugs is that a larger part of the receiver, between chamber and lugs, must be made stronger and heavier to resist stretching forces. Also,
9880-462: The bolt handle or bolt guide rib into a notch in the receiver , this method is still used in .22 rimfire rifles. The most common locking method is a rotating bolt with two lugs on the bolt head, which was used by the Lebel Model 1886 rifle , Model 1888 Commission Rifle , Mauser M 98 , Mosin–Nagant and most bolt-action rifles. The Lee–Enfield has a lug and guide rib, which lock on the rear end of
10010-407: The bolt in addition to the linear motions to perform chambering and primary extraction . The bolt locking of a straight pull action is achieved differently without needing manual inputs, therefore the entire operating cycle needs the shooter to perform only two movements (pull back and push forward), instead of four movements (rotate up, pull back, push forward, and rotate down), this greatly increases
10140-432: The bolt in place. The operation can be done via a rotating bolt , a lever, cam action, a locking piece, or a number of systems. Straight pull designs have seen a great deal of use, though manual turn bolt designs are what is most commonly thought of in reference to a bolt-action design due to the type ubiquity. As a result, the bolt-action term is often reserved for more modern types of rotating bolt designs when talking about
10270-409: The bolt into the receiver. The bolt knob is the part of the bolt handle that the user grips when loading and reloading the firearm and thereby acts as a cocking handle . On many older firearms, the bolt knob is welded to the bolt handle, and as such becoming an integral part of the bolt handle itself. On many newer firearms, the bolt knob is instead threaded onto the handle, allowing the user to change
10400-420: The bolt's housing. With the new design came a new dry fire method; instead of the bolt being turned up slightly, the action is locked back to catch the firing pin. The action was later used in the centre-fire Heym SR 30 . Typically, the bolt consists of a tube of metal inside of which the firing mechanism is housed, and which has at the front or rear of the tube several metal knobs, or "lugs", which serve to lock
10530-404: The bore axis, contributing to accuracy. The front opening of the case neck, which receives and fastens the bullet via crimping , is known as the case mouth . The closed-off rear end of the case body, which holds the primer and technically is the case base , is called the case head as it is the most prominent and frequently the widest part of the case. There is a circumferential flange at
10660-590: The bored-through cylinder is a Frenchman by the name of Perrin, who allegedly produced in 1839 a pepperbox revolver with a bored-through cylinder to order. Other possible claimants include Devisme of France in 1834 or 1842 who claimed to have produced a breech-loading revolver in that period though his claim was later judged as lacking in evidence by French courts and Hertog & Devos and Malherbe & Rissack of Belgium who both filed patents for breech-loading revolvers in 1853. However, Samuel Colt refused this innovation. White left Colt, went to Smith & Wesson to rent
10790-420: The brass malleable again ready for the next series of dies. Manufacturing bullet jackets is similar to making brass cases: there is a series of drawing steps with annealing and washing. Critical cartridge specifications include neck size, bullet weight and caliber , maximum pressure, headspace , overall length, case body diameter and taper, shoulder design, rim type , etc. Generally, every characteristic of
10920-407: The breech (rear end) of the barrel, as well as preventing potential propellant loss, contamination or degradation from moisture and the elements. In modern self-loading firearms , the cartridge case also enables the action mechanism to use part of the propellant 's energy (carried inside the cartridge itself) and cyclically load new rounds of ammunition to allow quick repeated firing. To perform
11050-458: The breech block. Other European powers adopted breech-loading military rifles from 1866 to 1868, with paper instead of metallic cartridge cases. The original Eley-Boxer cartridge case was made of thin-coiled brass—occasionally these cartridges could break apart and jam the breech with the unwound remains of the case upon firing. Later the solid-drawn, centerfire cartridge case, made of one entire solid piece of tough hard metal, an alloy of copper, with
11180-444: The case dimensions of a cartridge, this is usually referring to the cartridge's overall length (COL), which in turn dictates the minimal receiver size and operating space ( bolt travel) needed by the action , into either "mini-action", "short-action", "long-action" ("standard-action"), or " magnum -action" categories. The most popular material used to make cartridge cases is brass due to its good corrosion resistance . The head of
11310-436: The case head called a rim , which provides a lip for the extractor to engage. Depending on whether and how the rim protrudes beyond the maximum case body diameter, the case can be classified as either "rimmed", "semi-rimmed", "rimless", "rebated", or "belted". The shape of a bottleneck cartridge case (e.g. body diameter, shoulder slant angle and position, and neck length) also affects the amount of attainable pressure inside
11440-417: The case still containing a used-up primer, then gets ejected from the gun to clear room for a subsequent new round. A modern cartridge consists of four main components: the case , the projectile , the propellant , and the primer . The main defining component of the cartridge is the case, which gives the cartridge its shape and serves as the integrating housing for other functional components, it acts as
11570-414: The case, which in turn influences the accelerative capacity of the projectile. Wildcat cartridges are often made by reshaping the case of an existing cartridge. Straight-sided cartridges are less prone to rupturing than tapered cartridges , in particular with higher pressure propellant when used in blowback-operated firearms. In addition to case shape, rifle cartridges can also be grouped according to
11700-409: The chamber known as the "chamber neck", "chamber shoulder", and "chamber body". Some cartridges, like the .470 Capstick , have what is known as a "ghost shoulder" which has a very slightly protruding shoulder, and can be viewed as a something between a bottleneck and straight-walled case. A ghost shoulder, rather than a continuous taper on the case wall, helps the cartridge to line up concentrically with
11830-473: The commercial market post-war, numbering in the tens of millions by Remington in the unique, and most accurate Model 700, two of the others use the Mauser system, with other designs such as the Lee–Enfield system and the Mosin Nagant system, of only limited usage. The Mauser bolt-action system is based on 19th-century Mauser bolt-action rifle designs and was finalized in the Gewehr 98 designed by Paul Mauser . It
11960-686: The contained shots as a hail of sub-projectiles. Shotgun shots are usually made from bare lead, though copper/ zinc – coated steel balls (such as those used by BB guns ) can also be used. Lead pollution of wetlands has led to the BASC and other organizations campaigning for the phasing out of traditional lead shot. There are also unconventional projectile fillings such as bundled flechettes , rubber balls , rock salt and magnesium shards, as well as non-lethal specialty projectiles such as rubber slugs and bean bag rounds . Solid projectiles (e.g. slugs , baton rounds , etc.) are also shot while contained within
12090-413: The design's inherent potential for superior accuracy and precision , as well as ruggedness and reliability compared to self-loading designs. Most bolt-action firearms use a rotating bolt operation, where the handle must first be rotated upward to unlock the bolt from the receiver , then pulled back to open the breech and allowing any spent cartridge case to be extracted and ejected. This also cocks
12220-417: The earliest efficient modern cartridge cases was the pinfire cartridge , developed by French gunsmith Casimir Lefaucheux in 1836. It consisted of a thin weak shell made of brass and paper that expanded from the force of the explosion. This fit perfectly in the barrel and thus formed an efficient gas check. A small percussion cap was placed in the middle of the base of the cartridge and was ignited by means of
12350-737: The environment. In armor-piercing bullets , very hard and high-density materials such as hardened steel , tungsten , tungsten carbide , or depleted uranium are used for the penetrator core. Non-lethal projectiles with very limited penetrative and stopping powers are sometimes used in riot control or training situations, where killing or even wounding a target at all would be undesirable. Such projectiles are usually made from softer and lower-density materials, such as plastic or rubber . Wax bullets (such as those used in Simunition training) are occasionally used for force-on-force tactical trainings , and pistol dueling with wax bullets used to be
12480-451: The existing bolt handle. These are often made of either rubber or plastic. Most bolt-action firearms are fed by an internal magazine loaded by hand, by en bloc , or by stripper clips , though a number of designs have had a detachable magazine or independent magazine, or even no magazine at all, thus requiring that each round be independently loaded. Generally, the magazine capacity is limited to between two and ten rounds, as it can permit
12610-414: The faster rate of fire that all semi-automatic rifle alternatives allow. There are, however, many semi-automatic rifle designs used especially in the designated marksman role. Today, bolt-action rifles are chiefly used as hunting and target rifles. These rifles can be used to hunt anything from vermin to deer and to large game , especially big game caught on a safari , as they are adequate to deliver
12740-456: The firing mechanism. The evolving nature of warfare required a firearm that could load and fire more rapidly, resulting in the flintlock musket (and later the Baker rifle), in which the pan was covered by furrowed steel. This was struck by the flint and fired the gun. In the course of loading, a pinch of powder from the cartridge would be placed into the pan as priming, before the rest of the cartridge
12870-423: The first to be generally adopted was the British 1888 Lee–Metford . World War I marked the height of the bolt-action rifle's use, with all of the nations in that war fielding troops armed with various bolt-action designs. During the buildup prior to World War II , the military bolt-action rifle began to be superseded by semi-automatic rifles and later fully automatic rifles , though bolt-action rifles remained
13000-406: The flame passed through a small hole in the side of the barrel to ignite the main gunpowder charge. The last evolution was to use a small metallic cap filled with a shock sensitive explosive compound that would ignite with a hammer strike. The source of ignition could be a burning slow match ( matchlock ) placed onto a touch hole , a piece of pyrite ( wheellock )/ flint ( flintlock ) striking
13130-405: The front; it holds the primer at the back end, which receives an impact from a firing pin and is responsible for igniting the main propellant charge inside the case. While historically paper had been used in the earliest cartridges , almost all modern cartridges use metallic casing. The modern metallic case can either be a "bottleneck" one, whose frontal portion near the end opening (known as
13260-543: The gunsmiths Blanchard or Charles Robert. In the United States, in 1857, the Flobert cartridge inspired the .22 Short , specially conceived for the first American revolver using rimfire cartridges, the Smith & Wesson Model 1 . A year before, in 1856, the LeMat revolver was the first American breech-loading firearm, but it used pinfire cartridges, not rimfire. Formerly, an employee of
13390-477: The late 14th and early 15th centuries. Historians note their use by soldiers of Christian I, Elector of Saxony and his son in the late 16th century, while the Dresden Armoury has evidence dating their use to 1591. Capo Bianco wrote in 1597 that paper cartridges had long been in use by Neapolitan soldiers. Their use became widespread by the 17th century. The 1586 round consisted of a charge of powder and
13520-682: The late 19th century all the way through both World Wars , bolt-action rifles were the standard infantry service weapons for most of the world's military forces, with the exception of the United States Armed Forces , who used the M1 Garand Semi-automatic rifle . In modern military and law enforcement after the Second World War, bolt-action firearms have been largely replaced by semi-automatic and selective-fire firearms, and have remained only as sniper rifles due to
13650-421: The lead with a small percentage of tin or antimony can reduce such fouling, but grows less effective as velocities are increased. A cup made of harder metal (e.g. copper), called a gas check , is often placed at the base of a lead bullet to decrease lead deposits by protecting the rear of the bullet against melting when fired at higher pressures, but this too does not work at higher velocities. A modern solution
13780-442: The lower end of the power spectrum, although due to the low manufacturing cost some of them (e.g. .22 Long Rifle ) are among the most popular and prolific ammunitions currently being used. Centerfire primers are a separately manufactured component, seated into a central recess at the case base known as the primer pocket , and have two types: Berdan and Boxer. Berdan primers, patent by American inventor Hiram Berdan in 1866, are
13910-461: The magazine to be flush with the bottom of the rifle, reduce the weight, or prevent mud and dirt from entering. A number of bolt-actions have a tube magazine , such as along the length of the barrel. In weapons other than large rifles, such as pistols and cannons , there were some manually operated breech-loading weapons. However, the Dreyse Needle fire rifle was the first breech loader to use
14040-453: The mainstream primer designs, while the pinfire also still exists but only in rare novelty miniature guns and a few very small blank cartridges designed as noisemakers. In rimfire ammunitions, the primer compound is moulded integrally into the interior of the protruding case rim , which is crushed between the firing pin and the edge of the barrel breech (serving as the "anvil"). These ammunitions are thus not reloadable , and are usually on
14170-409: The mass of the cartridges can affect how much ammunition a soldier can carry, so the lighter steel cases do have a logistic advantage. Conversely, steel is more susceptible to contamination and damage so all such cases are varnished or otherwise sealed against the elements. One downside caused by the increased strength of steel in the neck of these cases (compared to the annealed neck of a brass case)
14300-560: The metallic cartridge bolt-action Gras rifle in 1874. European armies continued to develop bolt-action rifles through the latter half of the 19th century, first adopting tubular magazines as on the Kropatschek rifle and the Lebel rifle . The first bolt-action repeating rifle was patented in Britain in 1855 by an unidentified inventor through the patent agent Auguste Edouard Loradoux Bellford using
14430-438: The metallic cartridge was invented, the primer was relocated backward to the base of the case, either at the center of the case head ( centerfire ), inside the rim ( rimfire ), inside a cup-like concavity of the case base (cupfire), in a pin-shaped sideways projection ( pinfire ), in a lip-like flange ( lipfire ), or in a small nipple-like bulge at the case base ( teat-fire ). Today, only the centerfire and rimfire have survived as
14560-835: The original bolt knob for an aftermarket one, either for aesthetical reasons, achieving better grip or similar. The type of threads used vary between firearms. European firearms often use either M6 1 or M8 1.25 threads, for example M6 is used on the SIG Sauer 200 STR , Blaser R93 , Blaser R8 , CZ 457 and Bergara rifles, while M8 is used on the Sako TRG and SIG Sauer 404 . Many American firearms instead use 1/4" 28 TPI (6.35 0.907 mm) or 5/16" 24 TPI (7.9375 1.058 mm) threads. Some other thread types are also used, for example, No. 10 32 TPI (4.826 0.794 mm) as used by Mausingfield. There also exists aftermarket slip-on bolt handle covers which are mounted without having to remove
14690-616: The outside, making it difficult (or even impossible) to fire the gun in rainy or humid conditions as wet gunpowder burns poorly. After Edward Charles Howard discovered fulminates in 1800 and the patent by Reverend Alexander John Forsyth expired in 1807, Joseph Manton invented the precursor percussion cap in 1814, which was further developed in 1822 by the English-born American artist Joshua Shaw , and caplock fowling pieces appeared in Regency era England. These guns used
14820-469: The primary weapon of most of the combatants for the duration of the war; and many American units, especially the USMC , used bolt-action M1903 Springfield rifles until sufficient numbers of M1 Garand rifles were made available. The bolt-action is still common today among many sniper rifles , as the design has the potential for superior accuracy, reliability, reduced weight, and the ability to control loading over
14950-450: The projectile is the effector component of the cartridge, and is actually responsible for reaching, impacting, and exerting damage onto a target. The word "projectile" is an umbrella term that describes any type of kinetic object launched into ballistic flight , but due to the ubiquity of rifled firearms shooting bullets, the term has become somewhat a technical synonym for bullets among handloaders . The projectile's motion in flight
15080-499: The projectiles and propellant were carried separately and had to be individually loaded via the muzzle into the gun barrel before firing, then have a separate ignitor compound (from a burning slow match , to a small charge of gunpowder in a flash pan , to a metallic percussion cap mounted on top of a "nipple" or cone), to serve as a source of activation energy to set off the shot. Such loading procedures often require adding paper/cloth wadding and ramming down repeatedly with
15210-448: The reloading procedure and paved the way for semi- and full-automatic firearms. However, this big leap forward came at a price: it introduced an extra component into each round – the cartridge case – which had to be removed before the gun could be reloaded. While a flintlock, for example, is immediately ready to reload once it has been fired, adopting brass cartridge cases brought in the problems of extraction and ejection. The mechanism of
15340-406: The right side and the charging handle on the left. The pistol grip itself, however, was made to be ambidextrous , such that the pistol also could be fired comfortably by left handed shooters. The model 501/502F Striker was produced from 2000 to 2005 and chambered for .22 LR (Model 501F) and .22 WMR (Model 502F) with 5 eller 10 round magazines. Its total length was 480 mm (18.6 inches), with
15470-580: The third locking lug and feature a "cock on closing" operation. The Lee–Enfield bolt-action system was introduced in 1889 with the Lee–Metford and later Lee–Enfield rifles (the bolt system is named after the designer James Paris Lee and the barrel rifling after the Royal Small Arms Factory in the London Borough of Enfield ), and is a "cock on closing" action in which the forward thrust of
15600-538: The third safety locking lug, to simplify production. The controlled-feed on the Mauser M 98 bolt-action system is simple, strong, safe, and well-thought-out design that has inspired other military and sporting rifle designs that became available during the 20th century, including the: Versions of the Mauser action designed prior to the Gewehr 98's introduction, such as that of the Swedish Mauser rifles and carbines, lack
15730-442: The use of metal cartridges. The development by Smith & Wesson (among many others) of revolver handguns that used metal cartridges helped establish cartridge firearms as the standard in the United States by the late 1860s and early 1870s, although many continue to use percussion revolvers well after that. Most of the early all-metallic cartridges were of the pinfire and rimfire types. The first centerfire metallic cartridge
15860-406: The years leading up to World War II, the Lee–Enfield bolt system was used in numerous commercial sporting and hunting rifles manufactured by such firms in the United Kingdom as BSA, LSA, and Parker–Hale, as well as by SAF Lithgow in Australia. Vast numbers of ex-military SMLE Mk III rifles were sporterised post WWII to create cheap, effective hunting rifles, and the Lee–Enfield bolt system is used in
15990-404: Was 570 mm (22.5 inches) (or 610 mm (1 foot) for the rear grip version) and 360 mm barrel (14 inches). It was delivered with a mount for attaching a scope sight. Model variants included: 510F, 516FSAK, 516FSS, 516FSAK and 516BSS. It was short action, with different bolt heads depending on the caliber group rim size and used a standard small shank Savage barrel. The factory trigger setup
16120-675: Was changed multiple times over the course of production. Bolt action Bolt-action is a type of manual firearm action that is operated by directly manipulating the bolt via a bolt handle , most commonly placed on the right-hand side of the firearm (as most users are right-handed ). The majority of bolt-action firearms are rifles , but there are also some variants of shotguns and handguns that are bolt-action. Bolt-action firearms are generally repeating firearms , but many single-shot designs are available particularly in shooting sports where single-shot firearms are mandated, such as most Olympic and ISSF rifle disciplines. From
16250-404: Was gradually developed, and used, first in a steel cap, and then in a copper cap, by various gunmakers and private individuals before coming into general military use nearly thirty years later. The alteration of the military flint-lock to the percussion musket was easily accomplished by replacing the powder pan with a perforated nipple and by replacing the cock or hammer that held the flint with
16380-419: Was invented by Jean Samuel Pauly in the first decades of the 19th century. However, although it was the first cartridge to use a form of obturation , a feature integral to a successful breech-loading cartridge, Pauly died before it was converted to percussion cap ignition. Frenchman Louis-Nicolas Flobert invented the first rimfire metallic cartridge in 1845. His cartridge consisted of a percussion cap with
16510-416: Was rammed down the barrel, providing charge and wadding. Later developments rendered this method of priming unnecessary, as, in loading, a portion of the charge of powder passed from the barrel through the vent into the pan, where it was held by the cover and hammer. The next important advance in the method of ignition was the introduction of the copper percussion cap . This was only generally applied to
16640-462: Was the first to introduce ammunition loaded with nitrocellulose-based smokeless powder ), and the Berthier series of rifles. Straight-pull bolt-actions differ from conventional turn-pull bolt-action mechanisms in that the bolt can be cycled back and forward without rotating the handle and thus only a linear motion is required, as opposed to a traditional bolt-action, where the user has to axially rotate
16770-513: Was ultimately considered too complicated for issue to soldiers and was supplanted by the Springfield Model 1861 , a conventional muzzle loading rifle. During the American Civil War, the bolt-action Palmer carbine was patented in 1863, and by 1865, 1000 were purchased for use as cavalry weapons. The French Army adopted its first bolt-action rifle, the Chassepot rifle , in 1866 and followed with
16900-572: Was used by Norway, Denmark, and briefly the United States. It is unusual among bolt-action rifles in that is loaded through a gate on the right side of the receiver, and thus can be reloaded without opening the bolt. The Norwegian and Danish versions of the Krag have two locking lugs, while the American version has only one. In all versions, the bolt handle itself serves as an emergency locking lug. The Krag's major disadvantage compared to other bolt-action designs
