The Federal Premium Gold Medal .223 Remington 69-grain Sierra MatchKing Boat-Tail Hollow Point (BTHP) Brass 20-round box is a specialized centerfire rifle cartridge engineered specifically for competitive precision shooting, long-range marksmanship, and mid-range tactical training. A primary technical challenge with standard factory .223 Remington ammunition is high velocity variance and projectile concentricity flaws, which cause erratic vertical stringing and unpredictable wind drift at extended ranges. Federal completely overcomes these ammunition vulnerabilities by pairing Sierra's world-renowned MatchKing projectiles with match-grade Gold Medal primers and micro-metered propellants, delivering tight standard deviations that match custom handloads.
The core technical advantage relies on extreme projectile symmetry combined with low-drag aerodynamic profile engineering. Built with an exceptional jacket concentricity tolerance within ±0.0003 inches, the 69-grain Sierra MatchKing BTHP eliminates rotational mass imbalance and minimizes in-flight yaw. Featuring a sleek boat-tail base, a small precision-meplat hollow point, and a 0.301 G1 ballistic coefficient, this projectile cuts through air resistance to retain velocity and resist wind cross-currents. Stabilizing best in rifle barrels with a 1:9" twist rate or faster, it yields sub-MOA precision and repeatable, flat downrange trajectories.
Launched at a stout muzzle velocity of 2,950 FPS, this match-grade cartridge is optimized for smooth, non-binding mechanical cycling across bolt-action precision rifles and modern sporting rifle (AR-15) platforms. Assembled in uniform, reloadable virgin brass cases fitted with temperature-stable, clean-burning propellants and benchrest-quality Gold Medal primers, it delivers uniform ignition pressures across diverse field temperatures. The precision-drawn brass cases ensure optimal chamber fit, consistent neck tension, and flawless extraction when shot placement is paramount.
