Shell Shock Technologies Launches .338 Lapua NAS³™ Cartridge Cases

New lightweight .338 Lapua two-piece case delivers increased internal capacity and higher velocities for civilian, military, and law enforcement marksmen.

Eubank, Ky. (May 2026) – Shell Shock Technologies, LLC. (SST), a leading innovator in the ammunition industry, today announced the commercial release of its .338 Lapua NAS³™ cartridge cases, now available online in quantities from 250 to 5,000. The launch extends SST’s revolutionary NAS³ two-piece technology – a corrosion-resistant nickel-alloy body locked to an ultra-durable stainless-steel head – into one of the most demanding long-range calibers used by precision rifle competitors, military sniper teams, and law enforcement tactical units.

The .338 Lapua NAS³ unloaded case delivers unmatched durability, reduced weight, and repeatable precision that outperforms traditional brass in every critical category. The cases are approximately 30 percent lighter than traditional brass and offer roughly 11 percent more internal volume, allowing more efficient energy use when powder is ignited. The result is the ability to achieve higher velocities at standard SAAMI pressures, with customers reporting standard-bullet velocities up to approximately 3,125 feet per second.

“The .338 Lapua has been the benchmark for long-range performance for decades, and our NAS³ platform takes it into a new performance class,” Peter Foss, Managing Partner and CEO of Shell Shock Technologies. “By increasing internal case capacity by roughly 11 percent and reducing case weight by about 30 percent, we’re giving shooters meaningful velocity gains and tighter shot dispersion. For military and law enforcement teams, that translates to extended effective range without compromising safety or reliability. For civilian precision shooters and competitive marksmen, it means a more consistent, longer-lasting case at a better cost per round.”

Manufactured to exacting tolerances, each .338 Lapua NAS³ case delivers consistent internal volume, concentricity, and neck tension, the foundation of the tight velocity spreads required for sub-MOA accuracy at extended distances. The two-piece case construction is engineered to be lightweight, corrosion-resistant, and gentle on extractors, supporting flawless extraction and smooth ejection through repeated firing cycles.

Key features of the .338 Lapua NAS³ cartridge cases include:

• Two-piece construction: corrosion-resistant nickel alloy body locked to an ultra-durable stainless-steel head.
• Approximately 30 percent lighter than traditional brass for reduced carry weight in the field without sacrificing strength.
• Roughly 11 percent more internal capacity, enabling higher velocities at standard SAAMI pressures.
• Match-grade dimensional consistency for repeatable ignition and tighter group sizes.
• Designed for easy loading and extended service life, the unloaded cases reduce waste and lower total cost per round.
• Compatible with standard .338 Lapua Magnum load data and the full range of commercial, match, and tactical projectiles.

From open-country big-game hunting and long-range competition to military special operations and law enforcement counter-sniper deployments, the .338 Lapua NAS³ case is designed for the demands of high-pressure, high-volume shooting environments. Reduced case weight supports faster movement for dismounted operators, while extended service life supports cost-conscious civilian handloaders and high-round-count training programs.

Shell Shock .338 Lapua NAS³ unloaded cartridge cases are available now in quantities of 250, 500, 1,000, 2,500, and 5,000 directly from Shell Shock Technologies. For all larger orders, please email SST@shellshocktech.com.
