Shell for bullets of automatic or semiautomatic firearms with intertial closure

摘要

A shell for bullets of automatic or semiautomatic firearms with inertial closure, comprising a hollow cylindrical body which is closed, at one of its axial ends, by a head and is adapted to accommodate a bullet at the opposite axial end, the head being centrally provided with a cap that accommodates the primer. At least the portion of the shell which is extracted from the firing chamber when the fired bullet leaves the barrel is provided with reinforcement means to prevent accidental bursting of the shell at the end of the firing action and when the extraction of the shell from the firing chamber begins.
