Remington UMC .300 AAC Blackout ammunition (brand part no. 20111) loads a 220-grain Open Tip Flat Base bullet at 940 fps, landing squarely in subsonic territory for shooters running a suppressor. Remington builds these on brass cases and packages them in the 160-round Freedom Bucket, a bulk format made for high-volume range days without constantly restocking boxes. Loaded right here in the USA, UMC ammunition is built for varmint hunting, training, and any situation where you need consistent quality at high volume. In .300 Blackout rifle ammunition for suppressed platforms, this subsonic load is the one shooters reach for first.
