Barnes .223 Remington 77-grain Match Burner OTM BT ammunition (part no. 32018) loads a heavy-for-caliber match bullet for AR-15 shooters who want serious accuracy at extended range. Barnes builds this 77-grain Match Burner as an open-tip boat-tail bullet, engineered purely for consistency and precision, and its heavier weight carries a higher ballistic coefficient than typical 55 to 62-grain .223 loads for less wind drift downrange. At approximately 2,670 feet per second, it still runs at a practical velocity for most .223/5.56 AR-15 barrels. In rifle ammunition for precision AR-15 shooting, this is a heavier-bullet answer built for the target line.

Key Specifications

Frequently Asked Questions

Will a 77-grain bullet stabilize in any .223/5.56 barrel? Heavier bullets like this one generally need a faster rifling twist rate, commonly 1:8 or 1:7, to stabilize properly, so it is worth checking your barrel’s twist before shooting a case.

Is the Match Burner bullet built to expand on impact? No, it is an open-tip match bullet built purely for accuracy and consistency, not for hunting-style expansion.
