Metal injection molded cased telescoped ammunition

A method for producing a cartridge case, the method comprising:

• using an analytical technique to generate variables representing factors and characteristics associated with enabling a cartridge case to be made via a Metal Injection Molding (MIM) process and to enable the MIM generated cartridge case to function properly during subsequent use as ammunition in a weapon, the analytical techniques comprising:
• generating baseline parameters of known cartridge case designs, the parameters including firing, extraction, and recovery performance;
• generating MIM cartridge parameters representing firing, extraction, and recovery performance of MIM cartridge cases;
• and
• down-selecting a MIM material for use in the MIM process based on a comparison between the baseline parameters and the MIM cartridge parameters:
• subjecting the down-selected MIM material to the MIM process to form the MIM cartridge case having an elongated member with a head at its first end, a mouth at its second end, and a body lying between the head and the mouth, wherein:
• the body further comprises sidewalls conjoined with a base to form a hollow cavity;
• the head further comprises the base;
• the mouth is further configured to receive a projectile;
• and
• the MIM cartridge case consists essentially of MIM material.
