Shotguns
A shotgun (also known as a scattergun, or historically as a fowling piece) is a long-barreled firearm designed to shoot a straight-walled cartridge known as a shotshell, which usually discharges numerous small pellet-like spherical sub-projectiles called shot, or sometimes a single solid projectile called a slug. Shotguns are most commonly smoothbore firearms, meaning that their gun barrels have no rifling on the inner wall, but rifled barrels for shooting slugs ( slug barrels) are also available. Shotguns come in a wide variety of calibers and gauges ranging from 5.5 mm (.22 inch) to up to , though the 12-gauge (18.53 mm or 0.729 in) and 20-gauge (15.63 mm or 0.615 in) bores are by far the most common. Almost all are breechloading, and can be single-barreled, double-barreled, or in the form of a combination gun. Like rifles, shotguns also come in a range of different action types, both single-shot and repeating. For non-repeating design ...

Automatic Shotgun
An automatic shotgun is an automatic firearm that fires shotgun shells (thereby making it a shotgun) and uses some of the energy of each shot to automatically cycle the action and load a new round. It will fire repeatedly until the trigger is released or ammunition runs out. Automatic shotguns have a very limited range, but provide tremendous firepower at close range. Design Automatic shotguns generally employ mechanisms very similar to other kinds of automatic weapons. There are several methods of operation, with the most common being gas, recoil, and blowback operated: * Gas operation uses the pressure of the gas (created by the burning propellant) behind the projectile to unlock the bolt assembly and then move it rearward. * Blowback operation uses the backward force applied by the projectile (due to Newton's Third Law of Motion) to retract the bolt assembly. * Recoil operation uses the backward force to retract the entire barrel and bolt assembly, which unlock at the re ...

Pump-action Shotgun
Pump action or slide action is a repeating firearm action that is operated manually by moving a sliding handguard on the gun's forestock. When shooting, the sliding forend is pulled rearward to eject any expended cartridge and typically to cock the hammer/ striker, and then pushed forward to load (''chamber'') a new cartridge into the chamber. Most pump-action firearms use an integral tubular magazine, although some do use detachable box magazines. Pump-action is typically associated with shotguns, although it has been used in rifles and other firearms as well. Because the forend is manipulated usually with the support hand, a pump-action gun is much faster than a bolt-action and somewhat faster than a lever-action, as it does not require the trigger hand to be removed from the trigger while reloading. Also because the action is cycled in a linear fashion, it creates less torque that can tilt and throw the gun off aim when repeat-firing rapidly. History The first slide a ...

Firearm
A firearm is any type of gun designed to be readily carried and used by an individual. The term is legally defined further in different countries (see Legal definitions). The first firearms originated in 10th-century China, when bamboo tubes containing gunpowder and pellet projectiles were mounted on spears to make the portable fire lance, operable by a single person, which was later used effectively as a shock weapon in the Siege of De'an in 1132. In the 13th century, fire lance barrels were replaced with metal tubes and transformed into the metal-barreled hand cannon. The technology gradually spread throughout Eurasia during the 14th century. Older firearms typically used black powder as a propellant, but modern firearms use smokeless powder or other propellants. Most modern firearms (with the notable exception of smoothbore shotguns) have rifled barrels to impart spin to the projectile for improved flight stability. Modern firearms can be described by their caliber ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Double Barreled Shotgun
A double-barreled shotgun is a break-action shotgun with two parallel barrels, allowing two single shots to be fired in quick succession or simultaneously. Construction Modern double-barreled shotguns, often known as ''doubles'', are almost universally break action, with the barrels hinge down at the rear to expose the breech ends for unloading and reloading. Since there is no reciprocating action needed to eject and reload the shells, doubles are more compact than repeating designs such as pump action, lever action, bolt action, or self-loading shotguns. Barrel configuration Double-barreled shotguns come in two basic configurations: * side-by-side (S×S) — the two barrels are arranged horizontally; * over-and-under (O/U) — the two barrels are arranged vertically. The original double-barreled guns were nearly all S×S designs, which was a more practical design for muzzleloaders. Early cartridge-firing shotguns also used the side-by-side action, because they kept t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Shotshell
A shotgun shell, shotshell or simply shell is a type of rimmed, cylindrical (straight-walled) cartridges used specifically in shotguns, and is typically loaded with numerous small, pellet-like spherical sub- projectiles called shot, fired through a smoothbore barrel with a tapered constriction at the muzzle to regulate the extent of scattering. A shell can sometimes also contain only a single large solid projectile known as a slug, fired usually through a rifled slug barrel. The hull usually consists of a paper or plastic tube often covered at the base by a metallic head cover which retains a primer, and the shot charge is typically contained by a wadding/ sabot inside the case. The caliber of the shotshell is known as its gauge. The projectiles are traditionally made of lead, but other metals such as steel, tungsten and bismuth are also used due to restrictions on lead, or for performance reasons such as achieving higher shot velocities by reducing the mass of ...

Shotgun Slug
A shotgun slug is a heavy projectile made of lead, copper, or other material and fired from a shotgun. Slugs are designed for hunting large game, and other uses, particularly in areas near human population where their short range and slow speed helps increase safety margin. The first effective modern shotgun slug was introduced by Wilhelm Brenneke in 1898, and his design remains in use today. Most shotgun slugs are designed to be fired through a cylinder bore, improved cylinder choke, rifled choke tubes, or fully rifled bores. Slugs differ from round ball lead projectiles in that they are stabilized in some manner. In the early development of firearms, smooth-bored barrels were not differentiated to fire either single or multiple projectiles. Single projectiles were used for larger game and warfare, though shot could be loaded as needed for small game, birds, and activities such as trench clearing. As firearms became specialized and differentiated, shotguns were still able to fi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Semi-automatic Shotgun
A semi-automatic shotgun is a repeating shotgun with a semi-automatic action, i.e. capable of automatically chambering a new shell after each firing, but requires individual trigger-pull to manually actuate each shot. Semi-automatic shotguns use gas-, blowback or recoil operation to cycle the action, eject the empty shell, and load another round. Many semi-automatic shotguns also provide an optional manual means of operation such as by pump action or a charging handle. Examples Notable semi-automatic shotguns include: * Akdal MKA 1919 * Armsel Striker-12 *Baikal MP-153 * Benelli M1014 *Beretta 1301 * Beretta AL391 * Beretta Xtrema 2 * Browning Auto-5 * Daewoo USAS-12 * Franchi Special Purpose Shotgun 12 * Franchi SPAS-15 * High Standard Model 10 * Ithaca Mag-10 * IWI Tavor TS12 * Mossberg 9200 * Mossberg 930 * Remington Model 1100 * Remington Model 11-87 * Remington Model SP-10 * Saiga-12 ("''Сайга-12''") *Sjögren shotgun * Smith & Wesson Model 1000 * SRM Arms M ...

Slug Barrel
A slug barrel is a shotgun barrel that is designed primarily to fire slugs instead of shot, and is usually rifled. A shotgun with such a barrel is often called a slug gun. Origins When slugs are fired in a standard, choked barrel, the slug is deformed by the choke as it exits. The degree of deformation is most acute with fuller chokes, which were among the most widely used in stock shotguns up until the 1980s and 1990s. Early shotgun slugs were "rifled" with deformable fins cast into the outside of the soft lead slug, which allowed the slug to swage down to fit the choke. With an open choke, the reduction in diameter is minimal, so accuracy does not suffer much; tighter chokes, however, deform the slug enough to impact accuracy significantly, and the impact of the slug on the choke (at velocities around 450 meters per second (1500 feet per second)) could also stretch the barrel with repeated firings. The first slug barrels The first slug barrels were cylinder bore barrels (no ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Break Action
Break action is a type of firearm action in which the barrel or barrels are hinged much like a door and rotate perpendicularly to the bore axis to expose the breech and allow loading and unloading of cartridges. A separate operation may be required for the cocking of a hammer to fire the new round. There are many types of break-action firearms; break actions are universal in double-barrelled shotguns, double-barrelled rifles, combination guns, and are also common in single shot pistols (especially derringers), rifles, shotguns, and can also be found in flare guns, grenade launchers, air guns, and some older revolver designs. They are also known as hinge-action, break-open, break-barrel, break-top, or, on old revolvers, top-break actions. Description Break action The first break-action revolver was patented in France and Britain at the end of December in 1858 by Devisme. A substantial hinge pin joins the two parts of the rifle or shotgun; the stock with its firing mechanism an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Repeating Firearm
A repeating firearm or repeater is any firearm (either a handgun or long gun) that is capable of being fired repeatedly before having to manually reload new ammunition into the weapon. Unlike single-shot firearms, which can only hold and fire one round, a repeating firearm can store multiple cartridges inside a magazine (either internal or detachable), a cylinder (as in revolvers) or a belt (as in machine guns), and uses a moving action to manipulate each cartridge into, and out of, battery position (within the chamber and in alignment with the bore). This allows the weapon to be discharged repeatedly, in relatively quick succession, before a manual ammunition reload is needed. Typically the term "repeaters" refers to the more ubiquitous single- barreled variants. Multiple-barrel firearms such as derringers, pepperbox guns, double-barreled rifles, double-barreled shotguns, combination guns, and volley guns can also hold and fire more than one cartridges (one in each ...
