Zero failures across the harshest testing conditions at the Naval Surface Warfare Center confirm NAS3 case technology’s battlefield readiness.
Eubank, KY (March 2025) – 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.
Together, these advanced case offerings deliver a generational leap in combat performance:
Reduced weight for increased mobility
Higher velocity and extended range
?Improved accuracy and consistency
SST continues to drive innovation in ammunition design, helping international defense and ammunition manufacturers gain a critical edge in today’s most complex operational environments.
