About Shell Shock Technologies NAS3 Cases:
NAS3 cases are 50 percent lighter than brass cases, offer greater lubricity, and will not abrade, clog, foul, wear out, or damage breach and ejector mechanisms. The cases offer greater corrosion resistance, tensile strength (2x stronger), and elasticity than brass. NAS3 cases will not split, chip, crack, or grow (stretch). The pistol cases are fully reloadable (using S3 Reload dies) and can be reloaded many more times than brass cases. NAS3 cases can be picked up with a magnet. The head can be colored for branding purposes and easy load identification.
NAS3 is “Best in Class” for maintaining consistent velocity between rounds. In an independent test performed by H.P. White Laboratory (a major munitions testing facility), rounds fired using NAS3 cases achieved a velocity standard deviation of 0.093 FPS (124-grain FMJ bullet, 4.2 grains Titegroup powder, ten rounds, extreme variation 3fps).
