Abstract: Disclosed is a cartridge case for various caliber ammunition that consists essentially of a powdered metal and/or powdered metal alloy that is formed into the cartridge case through an injection mold processing. Also disclosed is a method for forming a cartridge case, which may include use of Metal Injection Molding (“MIM”) processes to produce the cartridge case which retains a primer, propellant, and/or a bullet. The method can include metal injection molding an initial part, and also at least one of tapering and trimming the initial part to form the finished cartridge case. Further embodiments can include the use of Finite Element Method (FEM) analysis to develop an optimized MIM design.
