Common 12 gauge slug masses are 7 ⁄ 8 oz ((383 gr (24.8 g)), 1 oz ((437.5 gr (28.35 g)), and 1 + 1 ⁄ 8 oz ((492 gr (31.9 g)), the same as common birdshot payloads. Depending on the specific stack-up, a card wad is also sometimes located between the slug and the shotshell wad, depending largely on which hull is specified, with the primary ...
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 ...
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 ...
The US military M1030 breaching round is a 12-gauge, 2 + 3 ⁄ 4-inch (70 mm) shell that uses a 40-gram (1.4 oz) projectile made of powdered steel, bound with wax. [ 1 ] [ 2 ] The Clucas Method of Entry Hatton round is a 12-gauge, 3-inch (76 mm) magnum shell that uses a 43-gram (1.5 oz) frangible projectile, consisting of a high-density wax binder.
A slug is a term used for a bulky solid ballistic projectile. It is "solid" in the sense of being composed of one piece; the shape can vary widely, including partially hollowed shapes.

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]
One slug is a mass equal to 32.17405 lb (14.59390 kg) based on standard gravity, the international foot, and the avoirdupois pound. [3] In other words, at the Earth's surface (in standard gravity), an object with a mass of 1 slug weighs approximately 32.17405 lbf or 143.1173 N. [4] [5]
