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. Therefore, a 12 gauge is ...
For example, a typical 12-gauge shotgun slug is a blunt piece of metal that could be described as an 18 mm (.729 inch) caliber that weighs 28 grams (432 grains).

The weapon has two hammerless shotgun barrels with a single rifle barrel underneath, firing two 12 gauge or 16 gauge shotgun shells (16 gauge seems to have only been used on the commercial version) alongside a single 9.3×74mmR rifle round. The M30 has two triggers and a sliding selector directly behind the lever for opening the breech.
