The Barnes Suppressor Series Sierra MatchKing .300 Blackout ammunition is built specifically for shooters running suppressed rifles. Loaded to 1060 fps with a 220-grain hollow point bullet, this subsonic round prioritizes quiet operation and reliable cycling in suppressor-equipped firearms—whether you're running a bolt gun or a semi-automatic platform. Each box contains 20 rounds of purpose-built ammunition engineered around the realities of modern suppressed shooting.
Subsonic .300 Blackout can feel like a different cartridge depending on what you load into it. Barnes engineered this line with clean-burning propellants that reduce the gas signature and blowback that can gum up actions and reduce suppression effectiveness. That attention to propellant selection means less fouling and more consistent cycling through your semi-auto—a real benefit when you're shooting suppressed and want your gun to run cleanly for longer stretches.
The 220-grain MatchKing bullet is a proven design that delivers both accuracy and energy retention out to moderate distances. For hunters taking medium game from a suppressed platform, or shooters who simply want quiet, reliable subsonic ammunition for the range or field, this load offers the premium construction you'd expect from Barnes paired with Sierra's ballistic pedigree.

Yes. Loaded to 1060 fps, this Barnes Suppressor Series round is subsonic and designed specifically for suppressed rifles. The clean-burning propellants help reduce gas blowback through the action, which improves function and keeps your suppressor-equipped rifle running cleaner.
Barnes formulated this load with semi-auto cycling in mind. The propellant selection and subsonic velocity are designed to provide consistent function in suppressor-ready semi-automatic platforms, though function can vary based on your specific rifle's gas system and tune.
The Suppressor Series is engineered for target shooting and medium game hunting from suppressed rifles. The 220-grain MatchKing bullet offers both accuracy for range use and sufficient energy for field applications at typical suppressed-shooting distances.
Each box contains 20 rounds.
