Shell Shock Technologies has successfully tested its NEXT-GEN 7.62x51mm ammunition, achieving zero case failures under extreme conditions at the Naval Surface Warfare Center. The testing confirmed the durability and performance of the NAS3 cartridge cases used in high-pressure environments. The company aims to redefine military ammunition standards, with availability set for Summer 2025.
Shell Shock Technologies state ” Shell Shock Technologies, LLC. (SST), a leading innovator in the ammunition industry, is proud to announce a critical achievement in its mission to redefine military-grade ammunition performance. The company’s 7.62x51mm NAS3 cartridge cases have successfully completed rigorous testing at the Naval Surface Warfare Center, Crane Division, one of the most demanding environments in the defense sector. The results: zero case failures.
The tested ammo used a 155-gr bullet, loaded at 50,000 psi, and had velocities of 3000 ft/sec. It was tested under extreme pressure and velocity in belt-fed machine guns, including the 240 Bravo and Minigun platforms, SST’s 7.62×51 cases passed with flying colors, even under the violent conditions of automatic fire and harsh ejection cycles. Testing was conducted at ambient temperature, -40°F and +160°F, with all pressure and velocity benchmarks met or exceeded.
“This milestone underscores the durability, consistency, and tactical advantages of our NAS3 case technology,” said Peter Foss, Managing Director and CEO of Shell Shock Technologies. “Zero case failures in such unforgiving conditions is not just a win for us – it’s a validation for every warfighter and defense partner looking for lighter, faster, and more accurate ammunition.”
The 7.62x51mm success joins a growing list of calibers, including 300 BLK, 5.56, 6.5 Creedmoor, and the promising early results from .338 Lapua, that are reshaping battlefield expectations. The company is now ahead of schedule with initial test samples for the .338 Norma, and tooling is officially underway for .50 BMG. The 7.62x51mm will be available in Summer 2025.”
