Shell Shock brings its lightweight NAS3 case to .50 BMG

Shell Shock Technologies has added a .50 BMG case to its NAS3 line, pairing a nickel/stainless-steel base with an aluminum body. The company says it weighs about 40 percent less than brass and holds more powder.

The short version

According to Tactical Retailer, the .50 BMG Hybrid Case is aimed at military, law enforcement and extreme long-range shooters. The two-piece design uses aerospace-grade aluminum for the body, which increases internal case capacity compared with conventional brass. Independent testing cited by the company reached muzzle velocities of up to 3,111 fps with a 650-grain bullet at standard operating pressures. Shell Shock also says the corrosion-resistant construction helps extraction and lets cases cool faster during sustained fire.

• Construction: Nickel/stainless-steel base with an aerospace-grade aluminum body.
• Weight: About 40 percent lighter than conventional brass, according to the company.
