A 12-gauge shotgun refers to the diameter of the shotgun bore, with the gauge system indicating the number of lead balls of the bore's diameter that would weigh one pound. In a 12-gauge, it takes 12 lead balls of the same diameter to equal one pound. The bore diameter of a 12-gauge shotgun is approximately 0.729 inches (18.5 mm). This gauge is one of the most popular sizes for shotguns, commonly used for hunting and sport shooting.
