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 ...
Therefore with a 12-gauge, it would take 12 balls of lead of the same size as the 12 gauge shotgun's inner bore diameter to weigh 1 pound (454 grams). [1] The term is related to the measurement of cannons , which were also measured by the weight of their iron round shot ; an eight-pounder would fire an 8 lb (3.6 kg) ball.

A weld neck flange (also known as a high-hub flange [1] and tapered hub flange [2]) is a type of flange. There are two designs. The regular type is used with pipes. The long type is unsuitable for pipes and is used in process plant. [3] A weld neck flange consists of a circular fitting with a protruding rim around the circumference.
The normal variance in shotgun bore diameter means that fractional bores don't make much difference until you get to things well over a 10 gauge bore. The .410 bore, for example, is readily fired in many .45 Colt firearms (like the Thompson Center Arms Contender), and that's firing a 67.5 gauge shell in a 51 gauge barrel, and the nearly 10% ...
