Abstract:
One embodiment of the present invention provides a polymeric ammunition having a metal injection molded primer insert.

Claim (Index 1):
An ammunition having an injection molded primer insert comprising:\n an injection molded primer insert for polymer ammunition comprising\n a top surface opposite a bottom surface, \n a substantially cylindrical coupling element extending away from the bottom surface forming an interior surface inside the substantially cylindrical coupling element and \n an exterior surface, \n a primer recess in the top surface that extends toward the bottom surface, \n a primer flash aperture positioned in the primer recess to extend through the bottom surface, and \n a flange that extends circumferentially about an outer edge of the top surface, wherein the flange is adapted to receive a polymer overmolding, \n wherein the injection molded primer insert comprises 102, 174, 201, 202, 300, 302, 303, 304, 308, 309, 316, 316L, 316Ti, 321, 405, 408, 409, 410, 415, 416, 416R, 420, 430, 439, 440, 446 or 601-665 grade stainless steel; \n a polymeric middle body extending from primer insert to a cylindrical middle body coupling region molded from a first polymer, wherein the first polymer is molded over the flange, the inner circumferential surface into the primer flash hole aperture to the flash hole groove and the outer surface and extends to the cylindrical middle body coupling region; a diffuser inserted into the primer recess; a primer inserted into the primer flash hole aperture; a substantially cylindrical polymeric projectile end mated to the substantially cylindrical polymeric middle body, wherein the substantially cylindrical polymeric projectile end comprises a projectile end coupling region that extends to a shoulder region that reduces to a neck region having a projectile aperture wherein the projectile end coupling region couples to the middle body coupling region; a projectile frictionally fitted in the bullet-end aperture; a propellant chamber defined between the primer flash aperture and the projectile aperture; and a propellant at least partially filling the propellant chamber.
