Sierra 22 Cal 55gr SBT MatchKing

The Sierra 22 Cal 55gr SBT MatchKing is a high-performance component bullet crafted for precision handloaders, competition shooters, and long-range varmint hunters. Featuring a .224‑inch diameter, 55‑grain weight, and a hollow-point Spitzer boat-tail profile, this bullet delivers aerodynamic efficiency, match-grade consistency, and reliable terminal performance in .223 Remington, 22‑250 Remington, and similar small-bore platforms.

Built with a refined Spitzer ogive and tapered boat-tail base, the 55gr SBT achieves a G1 ballistic coefficient of approximately 0.360. This elevated BC reduces drag and wind drift, promoting sustained supersonic flight and flat trajectories—ideal for engaged shooting at ranges up to 500 yards.

Manufactured to Sierra’s exacting component tolerances—55.0 grains weight, 0.224″ diameter, approximately 0.940″ overall length, and sectional density near 0.159—the bullet maintains uniform jacket thickness, precise hollow-point geometry, and consistent boat-tail alignment. These features ensure tight shot groups, stable feeding, and consistent pressure performance in match-grade load development.

Optimized for barrels with twist rates between 1:8 and 1:14, the Sierra 22 Cal 55gr SBT MatchKing performs best at velocities between 2,700 and 3,200 fps. Handloaders consistently achieve sub‑½‑MOA accuracy, with dependable downrange precision and wind resistance—making it a top choice for benchrest shooting, competitive drills, and precision hunting.

As a component bullet, the Sierra 22 Cal 55gr SBT MatchKing gives reloaders full control over powder selection, primer choice, and seating depth—enabling tailored load development focused on trajectory accuracy, recoil balance, and targeted terminal effect. It is not factory-loaded ammunition but a high-precision Spitzer MatchKing component intended for elite small-bore performance.
