History
-Shotgun shells are generally measured by "gauge", which is the weight, in fractions of a pound, of a pure lead round ball that is the same diameter as the internal diameter of the barrel

Until the early 1960s. shotgun shells were using paper hulls and were nearly always roll crimped, although fold crimping also eventually became popular. The primers on these paper hull shotgun shells also changed from the pistol primers used on the early brass shotgun shells to a primer containing both the priming charge and an anvil, unlike rifle and pistol ammunition, making the shotgun shell primer taller. Card wads, made of felt and cork, as well as paperboard, were all used at various times, gradually giving way to plastic over powder wads, with card wads, and, eventually, to all plastic wads. Starting in the early 1960s, plastic hulls started replacing paper hulls for the majority of shotgun shells and by the 1980s, plastic hulls had become universally adopted.
