The move to steel shot reduced the use of 16 and 20 gauges for waterfowl hunting, and the shorter, 2 + 3 ⁄ 4-inch (70 mm), 12-gauge shells as well. However, the 3 + 1 ⁄ 2-inch (89 mm) 12-gauge shell, with its higher SAAMI pressure rating of 14,000 psi (97 MPa) compared to standard 2 + 3 ⁄ 4-inch (70 mm) and 3-inch (76 mm) 12-gauge shells ...
Loads of 12-gauge 00 buckshot are commonly available in cartridges holding from 8 (eight) to 18 (eighteen) pellets in standard lengths (2 + 3 ⁄ 4 inches, 3 inches, and 3 + 1 ⁄ 2). Reduced-recoil 00 buckshot is often used in tactical and self-defense rounds, minimizing shooter stress and improving the speed of follow-up shots.
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. These cartridges became wet in the muddy trench warfare environment; and swelled paper cases would no longer chamber reliably. Full-length brass cartridges proved more resistant ...
While the receiver length determines whether a shell will feed, the chamber length in the barrel determines if it will be safe to fire. For 12 gauge 870s, the maximum shell length is 2 + 3 ⁄ 4 in (70 mm) for non-magnums, 3 in (76 mm) for magnums, and 3 + 1 ⁄ 2 in (89 mm) for super magnums. Since barrels can be changed, it is important to ...

A typical round for defensive use would be a 12-gauge 2 + 3 ⁄ 4-inch (7.0 cm) length 00 buck shell, which contains 9 pellets roughly 8.4 millimetres (0.33 in) in diameter, each comparable to a .38 Special bullet in damage potential. New "tactical" buckshot rounds, designed specifically for defensive use, use slightly fewer shot at lower ...
