Description

SKU: USC300BLK220FMJSUB-200

US Cartridge’s 300 Blackout 220-grain subsonic FMJ ammo is built for shooters who need reliability, consistency, and quiet performance. Designed for suppressed shooting, these rounds stay below the sound barrier at 1015 fps, eliminating the supersonic crack that comes with standard rifle ammo. The result is a much quieter shot when paired with a suppressor, making it ideal for tactical use, hunting, or discreet training.

Unlike lighter supersonic loads, the 220-grain full metal jacket bullet maintains momentum at subsonic speeds, providing stable flight and smooth cycling in semi-automatic platforms. Each round is loaded into high-quality, newly manufactured brass casings, ensuring reliable chambering, clean extraction, and reloadability for those who prefer to reuse their brass. With a bulk pack of 200 rounds, this ammo offers extended range time without the hassle of frequent reloads, making it a practical choice for subsonic applications.
