Sierra 7.62mm 30 Cal 155gr HPBT PALMA MatchKing

The Sierra 7.62mm 30 Cal 155gr HPBT PALMA MatchKing is an elite precision component bullet tailored for Palma, Fullbore, and long-range competition shooting. Developed within Sierra’s revered MatchKing series, this .308‑inch, 155‑grain hollow-point boat-tail bullet meets the stringent specifications required for Palma-style matches and high-performance long-distance target setups.

Featuring a hollow-point meplat and optimized boat-tail base, the 155gr PALMA MatchKing achieves a G1 ballistic coefficient of approximately 0.435—minimizing wind drift and velocity decay. Its aerodynamic design supports flat trajectory and sustained supersonic flight through extended ranges. The .308″ diameter aligns with classic Palma cartridges such as .308 Winchester, 7.62×51 NATO, and target-modified 155gr loads.

Constructed to exacting factory tolerances—155.0 grains weight, 0.308″ diameter, approximately 1.035″ overall length, and a sectional density near 0.310—the bullet delivers unmatched consistency in concentricity, jacket uniformity, and meplat precision. The hollow-point profile facilitates consistent flight behavior, while the boat-tail enhances stability and reduces drag behind the base.

Engineered for full-power loads and heavy target-grade charges, the 155gr PALMA MatchKing is optimized for barrels with twist rates between 1:10 and 1:12, delivering sub‑½‑MOA accuracy when paired with precision brass and match primers. Shooters in Palma, Fullbore, and F‑Class disciplines rely on its unwavering performance and consistency under varying field conditions.

As a component bullet, the Sierra 7.62mm 30 Cal 155gr HPBT PALMA MatchKing gives handloaders full control over primer choice, powder type, and seating depth—enabling exacting load development to match match-grade trajectories, recoil patterns, and muzzle velocities. It is not factory-loaded ammunition but a competition-focused component for serious long-range shooters.

In summary, the Sierra 7.62mm 30 Cal 155gr HPBT PALMA MatchKing is a match-grade hollow-point boat-tail bullet specifically developed for Palma-style competition and long-range precision shooting. With its high ballistic coefficient, exacting tolerances, and handloader-driven load flexibility, this 155gr MatchKing variant is the preferred choice for shooters demanding top-tier, consistent performance at extreme distance.
