Shotgun shells are still rated in terms of the same archaic dram measurements, relative to their equivalence of smokeless powder load to a black-powder load weighed in drams.) John "Pondoro" Taylor mentioned in his book African Rifles and Cartridges that the 12 drams (328 gr., 3/4 oz., or 21 g.) charge would propel the projectile at around ...
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.
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 ...
A shotgun shell loaded with multiple metallic "shot", which are small, generally spherical projectiles. Shotgun slug: A single solid projectile designed to be fired from a shotgun. Baton round: a generally non-lethal projectile fired from a riot gun. Bullets
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 powder shotshell to an old shotshell using that number of drams of black powder.
While shotguns had been used in earlier conflicts, the trench warfare of World War I demonstrated a need for standardized weapons and ammunition. [2] Initial issue with each shotgun was one hundred commercial-production paper-cased shotgun shells containing nine 00 buckshot pellets 0.33 inches (8.4 mm) in diameter.
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]
Where RS (Rifle/Shotgun) is equivalent to FFg black powder and P (Pistol) is equivalent to FFFg black powder on the Fg (coarsest) to FFFFg (finest) granularity scale. While Pyrodex offers improved safety and increased efficiency (in terms of shots per pound of powder) over black powder, the level of fouling is similar to black powder as Pyrodex ...
