Winchester Super Clean NT 45 ACP ammunition delivers lead-free performance for shooters required to comply with indoor range restrictions or California Prop 65 regulations. This 160-grain full metal jacket load uses a zinc core bullet and lead-free primer, achieving 1100 feet per second and 430 foot-pounds of muzzle energy. Winchester builds the Super Clean NT line for training environments where traditional lead-core ammunition is prohibited, while maintaining the accuracy and function demanded by competitive shooters and law enforcement qualifications.
Built for the Box
The 160-grain FMJ bullet seats in reloadable brass cases with Boxer primers. The zinc core construction eliminates lead exposure at the firing line and downrange, meeting the requirements of ranges enforcing lead-free policies. Muzzle velocity of 1100 fps produces moderate recoil in full-size 45 ACP handguns, and the non-corrosive primer chemistry extends firearm service life. Each box contains 50 rounds, manufactured in the United States to SAAMI specifications.

This load fits shooters running 1911s, Glocks, SIGs, and M&P pistols on ranges enforcing lead-free mandates. The 160-grain projectile produces less barrel wear than heavier 230-grain loads, and the zinc core maintains jacket integrity through rifling.

Who It’s For
Competitive shooters training at indoor facilities with lead restrictions will log consistent groups with this load. Law enforcement agencies conducting quarterly qualifications under California AB 2494 or similar state mandates can budget training cycles without lead exposure concerns. Reloaders gain once-fired brass suitable for standard 45 ACP dies, and the Boxer primer pockets accept large pistol primers without modification.

- This ammunition contains lead-free components in both bullet and primer; store in original packaging and inspect cases for damage before loading.
