The United States (U.S.) Army Contracting Command – Rock Island (ACC-RI) on behalf of the Project Manager Maneuver Ammunition Support (PM-MAS), is hosting a Small Caliber High Pressure Cartridge Case Industry Day & Vendor Demonstration. This event will take place at the Army Research Laboratory (ARL) Aberdeen Proving Ground (APG), MM, and is schedule to start at 08:00 AM Eastern Time (ET) on July 09, 2025. Check-in the day of the event at the ARL, Bldg. 328, APG, MD.

The purpose of this event is to provide information regarding opportunities to fulfill upcoming requirements for a small caliber alternate cartridge casing, that can sustain High Pressures, while maintaining system reliability, safety function across a broad spectrum of environmental conditions and similar cost to existing brass casing.

The expected technologies may include, but not limited to 5.56mm, 6.8mm, .338NM, 7.62mm and Intermediate calibers, with pressure between 40%-100% above standard NATO case mouth pressures.

Participants interested in demonstrating their high pressure case can choose the host weapon system but must provide the required weapons/ammunition for testing. The Government will not provide any weapons or ammunition for use or demonstration.
