Did you know that it is also possible to make cartridge cases with the MIM (Metal Injection Molding) technology?
United Defense Corp.’s M-PACT (Molded Performance Alloy Case Technology) cases are MIM-produced, which, according to the company, provides superior structural strength to withstand extreme pressures and allows for tighter tolerances and improved consistency.
This technology may become a more cost-effective way of producing high-pressure cartridge cases compared to multi-component hybrid cases or the use of super alloys. That is, if it performs as advertised. Additionally, the company notes that MIM case construction allows for lighter-weight cartridge cases at standard pressures, 20–30% lighter than traditional brass cartridges.

The M-PACT cases will be initially available for 6.8x51mm, 6.5 Creedmoor and .308 Winchester cartridges. The company targets both military/LE and civilian markets.
No information on price is available at the time of writing. The M-PACT ammunition is expected to be available for pre-order and purchase beginning Q1 2026.
