To top it off, this ammo is designed to resist clogging when fired through heavy clothing and comes loaded in premium, bright nickel-plated brass for unmatched corrosion resistance and smooth feeding performance. Clean-burning powders are optimized to burn quickly to help reduce recoil and limit disruptive muzzle flash to minimize night blindness in low-light environments. Made in USA.
