A 12-gauge shotgun cartridge in a transparent plastic hull, allowing the contents to be seen. From left to right: brass, propellant, over-powder wad, shot wad, #8 birdshot, over-shot wad, and crimp. A shotgun cartridge, shotshell, or shell is a type of rimmed, cylindrical (straight-walled) ammunition used specifically in shotguns.
The minimum barrel length for shotguns in most of the U.S. is 18 inches (460 mm), and this barrel length (sometimes 18.5–20 in (470–510 mm) to increase magazine capacity and/or ensure the gun is legal regardless of measuring differences [3]) is the primary choice for riot shotguns. The shorter barrel makes the weapon easier to maneuver ...
Cartridges manufactured by Western Cartridge Company contained twenty flechettes 18.5 millimetres (0.73 in) long and weighing 7.3 grains (0.47 g) each. The flechettes were packed in a plastic cup with granulated white polyethylene to maintain alignment with the bore axis, and supported by a metal disk to prevent penetration of the over-powder ...
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.
Similarly to SLAP rounds (saboted light armor penetrator) which get their armor-piercing ability from the propulsion of a 7.62 mm tungsten heavy alloy bullet from a 12.7 mm barrel (.50 caliber) using a sabot with much more energy than is usually possible from a 7.62 mm round, HEIAP munitions utilize a similar theory with an added explosive ...
CCI .22LR snake shot loaded with No. 12 shot. Snake shot, rat shot, or dust shot, [1] more formally known as shotshell [2] (a name shared with the shotgun shell) or canister shot, refers to handgun and rifle cartridges loaded with lead shot canisters instead of bullets, intended for pest control (essentially small arms canister shot).
The Mossberg 500 is a series of pump-action shotguns manufactured by O.F. Mossberg & Sons. [1] The 500 series comprises widely varying models of hammerless repeaters, all of which share the same basic receiver and action, but differ in bore size, barrel length, choke options, magazine capacity, stock and forearm materials.
Most shotgun cartridges are measured in terms of shotgun gauge. Shotgun gauge is determined by the weight of a round lead ball that is sized to fit into its barrel. For example, the barrel of a 12-gauge shotgun is equal to the diameter of a 1/12 of a pound lead ball (0.729 in) and a 20-gauge can fit a 1/20 pound lead ball (0.615 in).
