Ammunition having a projectile made by metal injection molding
First Claim
1. An ammunition having a metal injection molded projectile and a metal cartridge case comprising:
- a metal ammunition cartridge comprising a body that enclose a propellant chamber, a primer recess in a bottom portion of the unitary body, a primer flash hole that connects the primer recess and the propellant chamber, and a projectile aperture in communication with the propellant chamber, wherein the metal ammunition cartridge comprises stainless steel, ceramic alloys, copper/cobalt/nickel/custom alloys, tungsten, tungsten carbide, carballoy, ferro-tungsten, titanium, cobalt, nickel, alumina oxide, zirconia and aluminum;
a primer inserted into the primer flash hole aperture;
a propellant at least partially filling the propellant chamber; and
a metal injection molded projectile frictionally fitted in the projectile aperture, wherein the metal injection molded projectile comprises a nose extending essentially symmetrically to a shoulder, and an essentially cylindrical bearing surface extending from the shoulder to a base, wherein the metal injection molded projectile comprises stainless steel, brass, ceramic alloys, copper/cobalt/nickel/alloys, tungsten, tungsten carbide, carballoy, ferro-tungsten, titanium, copper, cobalt, nickel, uranium, depleted uranium, alumina oxide, zirconia and aluminum.
