40 S&W Stainless Steel Cases (Primed)


In stock


These cases are Head Stamped “Novx”.  They are primed with a Genix Small Pistol primer and ready to be loaded.  The case body is Stainless Steel and the Base is Nickel Plated Aluminum.

This is NOT Loaded Ammunition.  This is only the Primed Case.

Shell Shock’s NAS3 cases are 50% 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, higher tensile strength (2x stronger) and more elasticity than brass. NAS3cases have been tested successfully to pressures over 50k psi. NAS3 cases eject cool to-the-touch and can be picked up with a magnet.

Currently we do not recommend reloading these cases.  These are new cases and should be loaded and fired one time.  Do not run an expander ball through the case mouth.  Improper loading will lead to base separation.
