Remington UMC 300 Blackout 220gr OTFB – 50 Rounds

Remington UMC 300 Blackout 220-grain ammunition delivers reliable subsonic performance for suppressed shooting and close-range applications. The Open Tip Flat Base (OTFB) projectile is engineered to remain subsonic, reducing sound signature when paired with a suppressor and minimizing the risk of baffle strikes. This load prioritizes accuracy and consistent cycling in bolt-action rifles, AR-15 pistols, and carbines chambered in 300 BLK.

UMC ammunition uses reloadable brass cases and non-corrosive primers, making it a practical choice for high-volume training or hog hunting where close engagement distances are the norm. Available in 50-round boxes or bulk cases of 400 rounds. Not optimized for rapid follow-up shots in semi-automatic platforms — verify reliable cycling in your specific firearm before committing to bulk purchases.
