A Remington 870 12 gauge with sighted cylinder bore barrel suitable for Foster slugs and buckshot. The "Foster slug", invented by Karl M. Foster in 1931, and patented in 1947 (U.S. patent 2,414,863), is a type of shotgun slug designed to be fired through a smoothbore shotgun barrel, even though it commonly labeled as a "rifled" slug. A rifled ...
A US Marine practices shotgun door-breaching techniques. A breaching round or slug-shot is a shotgun shell specially made for door breaching.It is typically fired at a range of 6 inches (15 cm) or less, aimed at the hinges or the area between the doorknob and lock and doorjamb, and is designed to destroy the object it hits and then disperse into a relatively harmless powder.
The United States Navy included rifled slug cartridges among 21st-century loads. Slugs from these 2.75 in (7.0 cm) cartridges have a muzzle velocity between 1,590 ft (480 m) and 1,770 ft (540 m) per second. [6]
For example, a shotgun is called "12-gauge" because a lead sphere that just fits the inside diameter of the barrel weighs 1 ⁄ 12 pound (38 g). This measurement comes from the time when early cannons were designated in a similar manner—a "12 pounder" would be a cannon that fired a 12-pound (5.4 kg) cannonball; inversely, an individual "12 ...
Gauge was determined from the weight of a solid sphere of lead that will fit the bore of the firearm and is expressed as the multiplicative inverse of the sphere's weight as a fraction of a pound, e.g., a one-twelfth pound lead ball fits a 12-gauge bore. Therefore with a 12-gauge, it would take 12 balls of lead of the same size as the 12 gauge ...
Individual soldiers were often forced to carry a breaching shotgun in addition to their standard-issue rifle, but the Masterkey removes this need. The system consists of a shortened Remington 870 12 gauge pump-action intended to be mounted under a firearm's barrel, similarly to the M203 grenade launcher. It has a 3-round internal tubular ...
Home-defense and law enforcement shotguns are usually chambered for 12-gauge shells, providing maximum shot power and the use of a variety of projectiles such as buckshot, rubber, sandbag and slug shells, but 20-gauge (common in bird-hunting shotguns) or .410 (common in youth-size shotguns) are also available in defense-type shotgun models ...
The FRAG-12 is a specialized 12-gauge shotgun shell which contains a small amount of high explosive to breach intermediate barriers, defeat light armored vehicles, and disrupt IEDs. [1] The shell was designed by the Special Cartridge Company in London, England.
