The gauge of a shotgun is the number of lead balls of the given bore diameter required to make up one pound weight. The most popular shotgun gauge is 12, which represents a bore diameter of 0,729 inches (18,2 mm). Confusingly a shotgun with a bore diameter of 0,410 inches (10,2 mm) is not described by its appropriate gauge but as a «four-ten». ................
