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). Using this method, a .410 bore is equivalent to a (hypothetical) 67-gauge, instead of the incorrectly labeled 36 gauge (0.506) in Europe and South America. [14] [15]
Ammunition is produced from a number of component parts such as bullets, cartridge cases, powders, and primers.

As a cartridge, internal-propellant caseless ammunition is only fired from gun barrels, either closed or recoilless, and achieves ballistic stabilization through longitudinal spinning (conservation of angular momentum), either by the use of driving bands and rifling or oblique nozzles for the propellant gas.

While as early as 1955 Keith had suggested a new, medium-powered ".41 Special" cartridge, this idea was passed over in favor of the higher-powered "Magnum" option, and the Special survives only as a custom wildcat cartridge, bearing roughly the same relation to the .41 Magnum as the .38 Special does to the .357 Magnum and as the .44 Special ...
