Barnes Suppressor Series Sierra GameKing rifle Ammunition .300 Blackout 205gr HP 1060 fps 20/ct

The Barnes Suppressor Series Sierra GameKing .300 Blackout ammunition is engineered specifically for shooters running suppressors. If you own a suppressed rifle and want ammunition that works *with* your sound signature rather than against it, this load pairs a proven Sierra GameKing 205-grain hollowpoint bullet with a clean-burning powder charge that reduces gas blowback and helps semi-auto firearms cycle reliably. The subsonic velocity of 1060 fps keeps the round below the sound barrier, allowing your suppressor to do its job without the report spike of supersonic rounds.

Barnes Suppressor Series loads are built for hunters and shooters who've invested in suppressor-ready rifles and want ammunition that respects that investment. The Sierra GameKing bullet is a solid choice for medium-game hunting, combining controlled expansion with reliable terminal performance. The 205-grain weight and 1060 fps velocity work in harmony with suppressed platforms—less concussive blast, better reliability, and noticeably quieter downrange.

Each box contains 20 rounds, packed to Barnes' quality standards. Whether you're zeroing a suppressed precision rifle, hunting with a silenced .300 Blackout, or shooting subsonic loads for hearing protection and neighbor relations, this ammunition is purpose-built for the job.
