Sierra 22 Cal 55gr HPBT MatchKing

The Sierra 22 Cal 55gr HPBT MatchKing is a precision component bullet designed for competitive shooters and handloaders who demand match-grade accuracy, aerodynamic performance, and reliable terminal consistency in small-bore rifles. Featuring a .224‑inch diameter and a hollow-point Spitzer boat-tail profile weighing 55 grains, this bullet delivers exceptional flight stability and tight grouping—ideal for varmint hunting, benchrest shooting, and long-range precision tasks.

Built with a streamlined Spitzer ogive, hollow-point cavity, and tapered boat-tail base, the 55gr HPBT MatchKing achieves a G1 ballistic coefficient near 0.360. This elevated BC minimizes drag and wind drift, enhances velocity retention, and supports supersonic stability across extended ranges. It is compatible with cartridges like .223 Remington, 22-250 Remington, and .224 Valkyrie.

Manufactured to Sierra’s stringent component tolerances—55.0 grains weight, 0.224″ diameter, approximately 0.940″ overall length, and a sectional density around 0.159—the bullet features uniform jacket thickness, precise hollow-point geometry, and consistent boat-tail construction. These attributes support repeatable seating, stable pressure performance, and sub‑½‑MOA accuracy in precision handloads.

Optimized for barrels with twist rates between 1:8 and 1:14, the Sierra 22 Cal 55gr HPBT MatchKing delivers tight groupings and reliable flight consistency at velocities between 2,700 and 3,200 fps. Handloaders report exceptional elevation and wind resistance along with dependable terminal performance on small game and varmint targets up to 500 yards.

As a component bullet, the Sierra 22 Cal 55gr HPBT MatchKing gives reloaders full control over powder choice, primer type, and seating depth—enabling customized load development to balance trajectory, recoil, and terminal effect. It is not factory-loaded ammunition but a high-performance Spitzer MatchKing component crafted for serious .22-caliber enthusiasts.
