The .300BLK Subsonic 220gr. Sierra MatchKing is an excellent round for bolt guns and suppressed AR platform rifles. The bullet travels below the speed of sound and is quieter than standard ammunition. The large 220gr Sierra MatchKing bullet brings stability in flight, the accuracy you expect, and large amounts of momentum to the target. When used with gas operated guns, it is strongly recommended that a suppressor is used when shooting to ensure the complete cycling function of the firearm.
Gorilla Ammunition 300 Blackout 125 Grain Sierra Matchking provides superior accuracy and consistency. Whether you’re target shooting or hunting, the Gorilla 300 Blackout gives you the reliability you desire.
