Eubank, KY (October 2026) – Shell Shock Technologies, LLC. (SST), a leading innovator in the ammunition industry, today announced that its .50 BMG (12.7x99mm) NAS3™ ammunition has successfully completed live-fire testing in a belt-fed machine gun. The cases and ammunition fed, fired, extracted, and cycled as designed, marking the final major validation SST sought before moving the .50 BMG NAS3 case into production. Following minor tooling refinements, the company expects to begin producing its first sample lots in November 2026.
The case’s nickel-stainless steel alloy construction also supports clean extraction, faster heat dissipation than brass, and corrosion resistance under sustained fire and adverse conditions.
The test was conducted by Detroit Ammo on Oct. 1, 2026, using an M2Hb belted machine gun, with 10 consecutive rounds fired. Belt-fed operation places different demands on a cartridge case than a test barrel or bolt-action rifle. In automatic fire, the case must withstand high-speed feeding from a linked belt, chambering, firing, and rapid extraction, cycle after cycle. The NAS3 case met each of those demands.

At approximately 33.7 grams, the .50 BMG NAS3case is roughly 40 percent lighter than a comparable brass case, saving approximately 46 pounds per 1,000 rounds.
For crew-served, belt-fed weapons, where crews carry, stage, and feed ammunition in volume, that reduction delivers direct logistics and mobility value.
