M-22 Subsonic from Winchester Ammunition
The M-22 Subsonic is designed specifically to function in semi-automatic firearms while remaining subsonic from both pistol and rifle length barrels. The new M-22 Subsonic™ features a 45-grain Black Plated Lead Round Nose bullet that has the equivalent energy of full velocity 36-grain rimfire products. In addition, the M-22 Subsonic utilizes non-corrosive priming and clean burning powder for reduced muzzle flash.
