Abstract:
One embodiment of the present invention provides a polymeric ammunition cartridge and methods of making and using the same. The cartridge includes a substantially cylindrical insert connected to a substantially cylindrical polymeric middle body. The substantially cylindrical insert includes a top surface opposite a bottom surface and a substantially cylindrical coupling element that extends from the bottom surface, a primer recess in the top surface that extends toward the bottom surface, a primer flash hole positioned in the primer recess to extend through the bottom surface, and a flange that extends circumferentially about an outer edge of the top surface. The substantially cylindrical polymeric middle body includes a substantially cylindrical polymeric bullet-end and a substantially cylindrical polymeric coupling end connected by a powder chamber, wherein the substantially cylindrical polymeric coupling end extends over the substantially cylindrical coupling element and covers a circumferential surface of the primer flash hole.

Claim (Index 24):
A method of making a metal primer insert for a polymeric ammunition cartridge comprising the steps of:\n providing an insert blank for milling; milling a top surface on the insert blank; milling a flange that extends circumferentially about an outer edge of the top surface; milling a outer channel adjacent to the flange that extends circumferentially about the insert blank, wherein the outer channel is adapted to receive a polymer overmolding; milling a substantially cylindrical coupling element that extends from the outer channel to a coupling tip; milling an inner coupling element from the coupling tip to a bottom surface, wherein the bottom surface is opposite the top surface, wherein the substantially cylindrical coupling element is adapted to receive a polymer overmolding; milling a primer recess in the top surface that extends toward the bottom surface; milling a primer flash aperture in the primer recess through the bottom surface; and milling a groove in the primer recess around the primer flash aperture adapted to receive a polymer overmolding.
