Doesn't a shotgun fire one bullet per round? Wouldn't it be better to say 'machine gun' in this context?
Found this on the web: United States Code (18 USC 921) defines the shotgun as "a weapon designed or redesigned, made or remade, and intended to be fired from the shoulder, and designed or redesigned and made or remade to use the energy of the explosive in a fixed shotgun shell to fire through a smooth bore either a number of ball shot or a single projectile for each single pull of the trigger."
