CCI is known in the shooting sports industry for having reliable ammunition that delivers exceptional performance time and time again. At 1050 feet per second and an energy rating of 98 ft. lbs. at the muzzle, CCI Sub-Sonic is quieter than most high speed hollow points, and its special nose cavity is designed for high retained weights and classic mushrooming at subsonic velocities. It's great for a variety of small game and works in any rimfire rifle or handgun that functions with CCI's standard velocity ammunition. This ammunition is new production and non-corrosive.
