Armscor USA Competition 300 Blackout ammunition delivers consistent, American-made rounds built for shooters who demand reliability at the range or in the field. This 300 Blackout load pairs a 220-grain hollow-point boat-tail (HPBT) projectile with quality brass and primers, engineered to cycle dependably in modern tactical rifles and precision platforms. Whether you're zeroing a new build, running suppressed subsonic loads, or stacking rounds for serious practice, this ammunition gives you the ballistics and repeatability you need without the premium markup of boutique brands.
The 220-grain bullet weight is the subsonic sweet spot for .300 Blackout—it stays below the sound barrier when fired through standard barrel lengths, making it an ideal choice for suppressed shooting where you want real subsonic performance, not just quiet-ish supersonic rounds. The HPBT design means better aerodynamics and more predictable trajectories downrange, whether you're dialing for precision work or rapid fire.
Armscor manufactures this ammunition domestically, so you're supporting U.S. production while keeping costs competitive. The case format—20 rounds per box, 10 boxes per case—makes it easy to stock up for range sessions or training cycles without committing to pallets. Clean-burning powders and consistent primer seating mean fewer flyers and easier load development if you ever decide to reload the brass.
