Winchester Super Suppressed .22 LR 45 Grain CPRN Rimfire Ammo was designed to function reliably in rimfire rifles and pistols equipped with sound suppressors. The 45-grain, black copper-plated, round-nose bullet shoots accurately, feeds reliably, and leaves minimum fouling in suppressor baffles, barrel, feed ramp, and mag lip, making it dependable ammunition for serious use. Subsonic velocities reduce noise as well as muzzle flash. Winchester Super Suppressed Rimfire Ammo has also been tested extensively to cycle in semi-auto firearms.
