Barnes Precision Match .300 AAC Blackout 220-grain Match Burner OTM BT ammunition (part no. 32134) loads a heavy, subsonic bullet built specifically for suppressed accuracy work. Barnes builds this 220-grain Match Burner as an open-tip boat-tail match bullet, engineered purely for consistency and precision rather than hunting-style expansion, and the heavy weight keeps it subsonic through most .300 Blackout barrel lengths for quiet, suppressor-friendly shooting. It is the round serious .300 Blackout shooters load when accuracy behind a can matters more than anything else. In rifle ammunition for suppressed precision work, this is a dedicated match-grade subsonic load.

Key Specifications

• The chambering is .300 AAC Blackout, an AR-15-compatible cartridge built to run supersonic or subsonic from the same magazine.
• The bullet weighs 220 grains, heavy enough to stay subsonic through most .300 Blackout barrel lengths.
• The bullet is Barnes’ Match Burner, an open-tip boat-tail design built purely for accuracy rather than expansion.
• The boat-tail profile improves ballistic coefficient, helping the subsonic bullet retain stability and energy downrange.
• The cases are brass, and each box holds 20 rounds, shipped 10 boxes to the case.
• Cost runs about $2.05 per round for a dedicated subsonic match bullet.
• This load is built for AR-15 rifles and pistols chambered in .300 AAC Blackout, particularly suppressor-equipped builds.
• The heavier, slower-moving bullet also reduces felt recoil compared to lighter supersonic .300 Blackout loads.
• The open-tip design keeps manufacturing cost lower than a bonded or lead-free monolithic subsonic bullet.
