The DoubleTap Colt Defense .300 AAC Blackout 125gr HP (DoubleTap part no. 300BLK125CT) loads a 125-grain hollow point in .300 AAC Blackout for personal defense and everyday carry. DoubleTap engineers this round around consistent, reliable expansion when a fight-stopping hit matters most. Loaded to a genuinely supersonic 2,400 feet per second, this Colt Defense round is built for AR pistols and SBR-length .300 Blackout rifles that need reliable expansion without giving up the caliber’s subsonic/suppressor versatility in other loadings. For rifle ammunition, this is a load built to feed and perform reliably out of a home-defense or duty-grade rifle.
