The Hornady American Gunner .300 AAC Blackout 125-grain HP Match 50-round box is a high-performance centerfire rifle cartridge engineered specifically for supersonic target shooting, precision training, and competitive match application in .300 BLK platforms. A primary friction point when shooting bulk or general-purpose .300 Blackout ammunition is velocity fluctuation and inconsistent gas port pressures, which cause vertical stringing and cycling hiccups in semi-automatic rifles. Hornady resolves these operational limitations by pairing its premium reloadable virgin brass cases with a balanced 125-grain Hollow Point Match projectile and tightly metered propellants, delivering uniform pressure curves, reliable cycling, and predictable point-of-impact.
The primary technical advantage centers on Hornady's 125-grain HP Match projectile design. Featuring an aerodynamic secant ogive profile, the bullet significantly minimizes atmospheric drag and crosswind deflection to preserve velocity downrange. The internal architecture utilizes AMP (Advanced Manufacturing Process) bullet jackets engineered with near-zero wall thickness variation, wrapped around a uniform swaged lead core. This high-concentricity design eliminates rotational imbalance during flight, drastically narrowing shot dispersion and eliminating mid-string flyers during rapid or sustained fire.
Launching its 125-grain HP Match projectile at a factory-rated 2,175 FPS muzzle velocity, this American Gunner loading provides a flat supersonic trajectory that maintains flight stability well past 200 yards. Assembled using precision-drawn reloadable virgin brass cases, clean-burning powders, and non-corrosive Boxer primers, the cartridge guarantees smooth feeding, positive extraction, and uniform cycling across AR-15 platforms, short-barreled rifles (SBRs), and bolt-action rifles, whether running suppressed or unsuppressed. It stands as a top-tier choice for tactical training, 3-gun competition, and match precision.
Key Benefits
- Hollow Point Match Projectile: High-concentricity AMP jacket and swaged core eliminate rotational imbalance for match-grade accuracy.
