Sierra 284 Cal 7mm 180gr HPBT MatchKing

The Sierra 284 Cal 7mm 180gr HPBT MatchKing is a premium component bullet from Sierra’s MatchKing series, engineered for precision handloaders seeking long-range accuracy, aerodynamic efficiency, and controlled terminal performance. Featuring a .284‑inch diameter and a 180‑grain hollow-point Spitzer boat-tail profile, this bullet excels in competitive shooting, precision hunting, and target applications.

With a refined Spitzer ogive and tapered boat-tail base, the 284 Cal 7mm 180gr HPBT MatchKing achieves a G1 ballistic coefficient of approximately 0.530. This high BC reduces drag and wind drift, delivering flatter trajectories and sustained supersonic flight at extended ranges. Its .284″ diameter is compatible with cartridge platforms such as 7mm Remington Magnum, 7mm-08 Remington, and 7mm PRC.

Manufactured to exacting tolerances—180.0 grains weight, 0.284″ diameter, approximately 1.160″ overall length, and a sectional density near 0.306—the bullet maintains concentricity, consistent jacket thickness, and precise boat-tail geometry. The hollow-point cavity supports consistent terminal expansion, while the Spitzer profile enhances flight stability and precision.

Optimized for barrels with twist rates between 1:9 and 1:10, this 180gr HPBT MatchKing delivers sub‑½‑MOA accuracy in bolt-action and precision semi-auto rifles. Shooters report reliable groupings and excellent wind resistance, making it a top choice for long-range hunting and benchrest-style competitions.

As a component bullet, the Sierra 284 Cal 7mm 180gr HPBT MatchKing gives reloaders full control over powder selection, primer choice, and seating depth—allowing precise tuning for trajectory, recoil, and terminal performance. It is not factory-loaded ammunition but a match-grade bullet component tailored for serious long-range shooters.
