Shotgun
A shotgun (also known as a scattergun, peppergun, or historically as a fowling piece) is a long gun, long-barreled firearm designed to shoot a straight-walled cartridge (firearms), cartridge known as a shotshell, which discharges numerous small spherical projectiles called shot (pellet), shot, or a single solid projectile called a shotgun slug, slug. Shotguns are most commonly used as smoothbore firearms, meaning that their gun barrels have no rifling on the inner wall, but rifled barrels for shooting Sabot (firearms), sabot slugs (slug barrels) are also available. Shotguns come in a wide variety of calibers and Gauge (firearms), 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 shotgun, double barreled, or in the form of a combination gun. Like rifles, shotguns also ...

Shotshell
A shotgun cartridge, shotshell, or shell is a type of rimmed, cylindrical (straight-walled) ammunition used specifically in shotguns. It is typically loaded with numerous small, spherical sub-projectiles called shot. Shotguns typically use a smoothbore barrel with a tapered constriction at the muzzle to regulate the extent of scattering. Some cartridges contain a single solid projectile known as a slug (sometimes fired through a rifled slug barrel). The casing usually consists of a paper or plastic tube with a metallic base containing the primer. The shot charge is typically contained by wadding inside the case. The caliber of the cartridge is known as its gauge. The projectiles are traditionally made of lead, but other metals like 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 the shot charge. Other unusual projectiles such as saboted flechettes, ru ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Shotgun Slug
A shotgun slug is a heavy projectile (a slug) 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 for the year 1875, 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 and hunting. As firearms became specialized and diffe ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

20-gauge
The 20-gauge shotgun, also known as 20 bore or 20 gauge, is a type of smoothbore shotgun. 20-gauge shotguns have a bore diameter of , while the 12-gauge has a bore diameter of . 12-gauge and 20-gauge shotguns are the most popular gauges in the United States. The 20-gauge is popular among upland game hunters, target shooters, and skeet shooters. Description Twenty lead balls of a 20-gauge shotgun bore weigh one pound, while just 12 lead balls of a 12-gauge shotgun bore weigh the same. A 20-gauge shotgun is more suitable for hunting certain types of game or for some hunters because it may have less felt recoil than an identical shotgun in a larger gauge, and guns may be smaller and weigh less, though this has changed since the introduction of the 3-inch magnum shotshell. Regarding the yellow body tube color that 20-gauge ammunition usually has, it has been reserved in SAAMI documentation saying "SAAMI has reserved yellow for 20 gauge ammunition" "This ammunition shall hav ...

Firearm
A firearm is any type of gun that uses an explosive charge and is designed to be readily carried and operated 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 explosive propellants. Most modern firearms (with the notable exception of smoothbore shotguns) have rifled barrels to impart spin to the projectile for improved flight stabili ...

Pump-action Shotgun
Pump action is a type of manual firearm action that is operated 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 or striker, and then pushed forward to load a new cartridge into the chamber. Most pump-action firearms use an integral tubular magazine, although some do use detachable box magazines. Pump-action firearms are typically associated with shotguns, although it has also been used in rifles, grenade launchers, and other types of firearms. A firearm using this operating mechanism is colloquially referred to as a pumpgun. Because the forend is manipulated usually with the support hand, a pump-action firearm 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 t ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Gauge (firearms)
The gauge (in American English or more commonly referred to as bore in British English) of a firearm is a unit of measurement used to express the inner diameter (bore diameter) and other necessary parameters to define in general a smoothbore Gun barrel, barrel (compare to caliber, which defines a barrel with rifling and its Cartridge (firearms), cartridge). The gauge of a shotgun is a list that includes all necessary data to define a functional barrel. For example, the dimension of the chamber, the shotgun bore dimension and the valid proof load and commercial ammunition, as defined globally by the Commission internationale permanente pour l'épreuve des armes à feu portatives, C.I.P.; defined in Great Britain by the ''Rules, regulations and scales applicable to the proof of small arms'' (2006) of Worshipful Company of Gunmakers, The London Proof House and Birmingham Proof House, The Birmingham Proof House, as referred in the Gun Barrel Proof Act 1978, Paragraph 6; and defined in ...

Double-barreled Shotgun
A double-barreled shotgun, also known as a double shotgun, is a break-action shotgun with two parallel barrels, allowing two single shots that can be fired simultaneously or sequentially in quick succession. 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 (specifically break-action), 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 commonly all side-by-side designs, which was a more practical design for muzzleloa ...

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 operation, blowback, or recoil operation to cycle the action, eject the empty shell, and load another round. The first semi-automatic shotgun was the Automatic-5 by Browning. 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 * 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''") * Sj ...

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 rea ...

Cartridge (firearms)
A cartridge, also known as a round, is a type of pre-assembled firearm ammunition packaging a projectile ( bullet, shot, or slug), a propellant substance ( smokeless powder, black powder substitute, or black powder) and an ignition device ( primer) within 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. 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 a projectile is called a '' blank''; one that is completely inert (contains no active primer and no propellant) is called a '' dummy''; one that ...

Sabot (firearms)
A sabot (, ) is a supportive device used in firearm/artillery ammunitions to fit/patch around a projectile, such as a bullet/slug or a flechette-like projectile (such as a kinetic energy penetrator), and keep it aligned in the center of the barrel when fired. It allows a narrower projectile with high sectional density to be fired through a barrel of much larger bore diameter with maximal accelerative transfer of kinetic energy. After leaving the muzzle, the sabot typically separates from the projectile in flight, diverting only a very small portion of the overall kinetic energy. The sabot component in projectile design is the relatively thin, tough and deformable seal known as a driving band or obturation ring needed to trap propellant gases behind a projectile, and also keep the projectile centered in the barrel, when the outer shell of the projectile is only slightly smaller in diameter than the caliber of the barrel. Driving bands and obturators are used to seal these fu ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
