3,000 .300 BLK Cases
Shell Shock’s NAS3 cases are up to 50% lighter than brass cases, improve accuracy and consistency, offer greater lubricity, and will not abrade, clog, foul, wear-out or damage breach and ejector mechanisms. The cases offer greater corrosion resistance, higher tensile strength (2x stronger) and more elasticity than brass. NAS3 cases eject cool to-the-touch and can be picked up with a magnet.

The bullet will only require a light crimp, the nickel alloy used in our case cylinder has a much higher tensile strength than brass and does not require the bullet be seated as deeply or crimped as hard as brass. If you find the bullet spins or appears lose after crimping it is a strong indication that the bullet is seated too deep in the case. Also several of our testers have reported that NAS3 cases may not require resizing to fit in certain gun chambers.
