Shotgun shells

History

Starting in the late 1870s, paper hulls began replacing brass hulls. Paper hulls remained popular for nearly a century, until the early 1960s. These shotgun cartridges using paper hulls were nearly always roll crimped, although fold crimping also eventually became popular. The primers on these paper hull cartridges also changed from the pistol primers used on the early brass shotgun shells to a primer containing both the priming charge and an anvil, making the shotgun 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 from the early 1960s to the late 1970s, plastic hulls started replacing paper hulls for the majority of cartridges and by the early 1980s, plastic hulls had become universally adopted.
