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.
