Rem Umc 300blk 220gr Otfb 20/200

Remington UMC 300 Blackout 220-grain open-tip flat-base ammunition delivers cost-effective performance for suppressed rifle systems, subsonic applications, and high-volume training. Manufactured in the USA, this centerfire rifle ammunition balances affordability with consistent ballistics across 20-round boxes, making it suitable for operators running 300 Blackout platforms who prioritize economical round counts without quality compromise.

The 220-grain bullet weight in 300 Blackout is optimized for subsonic velocities, remaining below the sound barrier when fired from standard-length barrels without sacrificing down-range energy. Open-tip flat-base (OTFB) construction provides reliable feeding in magazine-fed systems and consistent terminal behavior in controlled environments. Each box contains 20 rounds, packaged for shooters who run dedicated 300 BLK upper receivers or complete rifle systems and need dependable ammunition for qualification cycles, suppressed duty drills, or extended range sessions.

This ammunition serves tactical trainers, law enforcement marksmen, military personnel, and civilian shooters operating in subsonic duty or training configurations. The 300 Blackout cartridge itself offers significant advantages in suppressed applications—lower noise signature, reduced recoil impulse, and terminal performance within effective combat ranges—while Remington's established manufacturing standards ensure consistent primer ignition and powder charge uniformity across production lots.

UMC (Union Metallic Cartridge) ammunition represents Remington's value-tier centerfire offering, engineered to deliver acceptable accuracy and reliability for high-round-count scenarios where specialty ammunition economics become prohibitive. For shooters evaluating 300 Blackout subsonic options, this product balances domestic manufacturing, known brand support, and per-round cost efficiency.
