The Winchester Super Suppressed SUP300BLK is purpose-built for suppressed firearms, delivering clean, quiet, and consistent performance. This subsonic, 200-grain load boasts a muzzle velocity of 1,060 fps, keeping the round below the speed of sound to significantly reduce the signature you hear when shooting with a suppressor.

Packaging comes in 20-round boxes, making it convenient for both training sessions and tactical use.
