Remington Subsonic .300 AAC Blackout Rifle Ammunition (Remington part no. 28430) loads a 220 grain open-tip flat base bullet at a rated 940 fps, developed jointly by Remington and AAC to run quietly and consistently through a suppressor. This load caters to the suppressor user or anyone who just wants a dependable, consistent subsonic round that stays below the sound barrier and skips the sharp supersonic crack. The OTFB bullet design eliminates exposed lead at the bullet’s heel, which helps cut down on leading inside a suppressor over repeated use, and Remington holds velocity to a tight tolerance so every round performs the same way. It’s a straightforward choice for suppressed .300 Blackout rifles and pistols built around quiet, subsonic performance.
