The Federal Premium Gold Medal .308 Winchester 168-grain Sierra MatchKing Boat-Tail Hollow Point (BTHP) Brass 20-round box is the gold-standard centerfire rifle cartridge engineered specifically for precision marksmanship, long-range competition, and tactical sniper training. A primary friction point with standard factory .308 Winchester ammunition is inconsistent bullet jacket concentricity and wide muzzle velocity variances, which cause unpredictable vertical dispersion and wind drift at extended ranges. Federal eliminates these accuracy-robbing variables by pairing Sierra's iconic MatchKing projectiles with benchrest-grade Gold Medal primers and micro-metered propellants, delivering match-winning, handload-level consistency straight out of the box.
The core technical advantage relies on extreme projectile symmetry combined with low-drag aerodynamic profile engineering. Built with ultra-tight jacket concentricity tolerances, the 168-grain Sierra MatchKing BTHP eliminates rotational mass imbalance to minimize in-flight yaw and stabilize barrel harmonics. Featuring a sleek boat-tail base, a small precision-meplat hollow point, and an impressive 0.462 G1 ballistic coefficient, this projectile cuts cleanly through air resistance to retain downrange speed, resist crosswind deflection, and ensure predictable, repeatable trajectory modeling out to 800 yards.
Exiting the muzzle at a stout 2,650 FPS, this match-grade load maintains exceptionally flat pressure curves across bolt-action precision rifles and modern semi-automatic tactical platforms (M1A / AR-10). Assembled in uniform, reloadable virgin brass cases fitted with temperature-stable, clean-burning propellants and legendary Federal Gold Medal match primers, it delivers consistent ignition pressures regardless of ambient field temperatures. The precision-drawn brass cases guarantee smooth chambering, optimal neck tension, and effortless extraction when sub-MOA grouping is non-negotiable.
