Remington UMC .300 AAC Blackout ammunition (brand part no. 20109) loads a 220-grain full metal jacket bullet at 1015 fps, a velocity that stays below the speed of sound for a genuinely subsonic loading. UMC ammunition is loaded right here in the USA and built for high-volume shooting: target practice, training drills, varmint work, or any range day where round count matters more than premium hunting performance. Staying subsonic gives this loading a quieter report and reduced recoil compared to standard-velocity .300 Blackout, an advantage that’s especially noticeable when run through a suppressor. For .300 Blackout shooters who want a genuine subsonic option in bulk, this rifle ammunition from Remington is built for exactly that.
