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 (453.6 g). [5] 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-pound (3.6 kg) ball.

While modern firearms are generally referred to by the name of the cartridge the gun is chambered for, they are still categorized together based on bore diameter. [citation needed] For example, a firearm might be described as a "30 caliber rifle", which could accommodate any of a wide range of cartridges using a roughly 0.30 inches (7.6 mm) projectile; or as a "22 rimfire", referring to any ...
The measurement .303 inches (7.7 mm) is the nominal size of the bore measured between the lands which follows the older black powder nomenclature. Measured between the grooves, the nominal size of the bore is .311 inches (7.9 mm). Bores for many .303 military surplus rifles are often found ranging from around .309 to .318 inches (7.8–8.1 mm ...
The bore cross section areas "Q" used in the calculations were taken from the appropriate C.I.P. data sheets. The intermediate cartridges .30 Carbine , 7.92×33mm Kurz , 7.62×39mm , 7.62×45mm , 5.45×39mm , .223 Remington / 5.56×45mm NATO and 5.8×42mm stand out as having relatively low sub 8 O ratio's .

This would imply a bore diameter of 1.052-inch (26.7 mm), however in practice the bore diameter varied greatly as, in muzzle loader days, shotgun gauges were custom made and often differed from the actual bore measurements. Commonly, 4 bores were closer to 0.935–0.955 in (23.7–24.3 mm) calibre, which is closer to 5 gauge.
