Abstract
A primer assembly including an ignition element assembly, a primer head assembly and a tubular body, is presented. The primer head assembly has an exterior diameter and an internal chamber containing the ignition element assembly. The tubular body has an open head end, a closed tail end and a wall defining an internal chamber. The internal chamber of the tubular body contains an ignition charge and the head end includes an internal diameter for receiving the exterior diameter of the primer head assembly. When the primer assembly is assembled, the tubular body encloses the primer head assembly and the primer head assembly seals the internal chamber. In one embodiment, the tubular body is a one-piece, seamless metallic tube having a wall of a thickness of about 0.150 to 0.160 inch and, preferably, about 0.155 inch.
