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" shot would in fact be a 1 ⁄ 12 pounder. Thus, a 10-gauge shotgun has a larger-diameter barrel than a 12-gauge shotgun, which has a larger ...
A dram is a unit of weight. The blackpowder charges of old shotshells were typically weighed in drams. Once semi-smokeless and smokeless powders were introduced, the weight of powder needed decreased for a given level of performance. So, shotshell makers advertised dram equivalents instead. This indicated the equivalent power of a smokeless ...
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 ...
Unlike the IZ-109 manually adjustable gas regulator system used on the Saiga-12, the gas system on the Vepr-12 is a clone of the IZ-433 unregulated fixed open port tappet system, allowing the Vepr-12 to cycle most commercially available 12-gauge loads, from 3.25 dram equivalent and up, without risking damage to the shotgun and without requiring ...
Military use of combat shotguns through the 20th century has created a need for ammunition maximizing the combat effectiveness of such weapons within the limitations of international law. 12-gauge has been widely accepted as an appropriate bore diameter to provide an effective number of projectiles within an acceptable recoil. Early 12-gauge ...
The brass cartridge cases contained three different types of loads: light at 12 drams, 14 drams at regular, and 16 drams of powder at heavy load. (Note: 1 dram = 27.34375 grains in the avoirdupois system, since 256 drams = 7000 grains = 1 pound of powder. Shotgun shells are still rated in terms of the same archaic dram measurements, relative to ...
Hence, a 12 gauge shotgun has a bore that is equivalent in diameter to a round shot of lead weighing one-twelth of a pound; a 20 gauge shotgun has a bore equivalent in diameter to a round shot of lead weighing one-twentieth of a pound, and so forth similarly sizing for 16 gauge and 10 gauge shotguns.
This is a table of selected pistol/submachine gun and rifle/machine gun cartridges by common name. Data values are the highest found for the cartridge, and might not occur in the same load (e.g. the highest muzzle energy might not be in the same load as the highest muzzle velocity, since the bullet weights can differ between loads).
