Remington UMC 300 AAC Blackout Subsonic 220 Grain OTFB Ammunition

Remington UMC 300 AAC Blackout subsonic ammunition delivers dependable, budget-friendly rounds for shooters who want serious performance without the premium price tag. Built around a 220-grain open tip flat base bullet, this load is purpose-built for subsonic shooting — ideal if you're running a suppressed rifle, shooting in noise-restricted areas, or hunting at ranges where supersonic crack matters. UMC (Umc stands for Remington's value line) has been a go-to for high-volume shooters and hunters since the 1980s, and for good reason: consistent construction, USA manufacturing, and the kind of reliability that keeps you downrange instead of troubleshooting.

The 220-grain subsonic profile in 300 Blackout hits the sweet spot for suppressed rifle work. Unlike full-power loads, subsonic ammo keeps velocity below the sound barrier — in this case, a muzzle velocity of 940 fps — so when paired with a quality suppressor, you get genuine hearing-safe performance. That makes it excellent for training, hunting hogs and predators, or simply putting rounds downrange without blasting everyone on the line. The open tip flat base bullet design is consistent and reliable, the kind of straightforward engineering that doesn't call attention to itself but doesn't let you down either.

Whether you're feeding a modern tactical rifle, an AR pistol, or a bolt gun, this Remington load won't break the bank, especially when buying by the box. Each box contains 50 rounds, so you can stock up for a full session at the range or in the field without feeling like you're gambling with your budget.
