Sierra 7.62mm 30 Cal 180gr SBT GameKing

The Sierra 7.62mm 30 Cal 180gr SBT GameKing is a high-performance component bullet engineered for handloaders and hunters who demand a versatile, mid-heavy .30-caliber bullet delivering accuracy, deep penetration, and aerodynamic efficiency. As part of Sierra’s GameKing line, this .308‑inch, 180‑grain Spitzer boat-tail bullet balances energy retention and downrange stability for medium to large-game engagement.

Featuring a streamlined Spitzer ogive and tapered boat-tail base, the 7.62mm 30 Cal 180gr SBT achieves a G1 ballistic coefficient approximately 0.445. This elevated BC produces flatter trajectory, reduced wind drift, and sustained supersonic flight within typical hunting distances. Its .308″ diameter ensures compatibility with popular cartridges such as .308 Winchester, 7.62×51 NATO, and 30-06 Springfield.

Manufactured to strict component tolerances—180.0 grains weight, 0.308″ diameter, around 1.200″ overall length, and a sectional density near 0.269—the bullet exhibits uniform jacket thickness, precise meplat alignment, and tight concentricity. The boat-tail geometry enhances flight stability and drag reduction, supporting repeatable sub‑MOA accuracy in bolt-action and precision semi-auto rifles.

Optimized for twist rates between 1:10 and 1:12, this bullet combines terminal reliability with precision. Hunters appreciate its balanced expansion and deep-penetration profile on game such as deer, elk, and hogs. The 180gr SBT GameKing holds its trajectory and energy well, making it a dependable choice across varying environments.

As a component bullet, the Sierra 7.62mm 30 Cal 180gr SBT GameKing gives reloaders full control over powder selection, primer choice, and seating depth—facilitating tailored load development for desired recoil, trajectory, and terminal effect. It is not factory-loaded ammunition; it is crafted for those seeking premium performance with component-level flexibility.

In summary, the Sierra 7.62mm 30 Cal 180gr SBT GameKing is an elite Spitzer boat-tail bullet offering aerodynamic excellence, consistent accuracy, and effective penetration on medium to large game. Ideal for precision hunters and long-range shooters, this 180gr GameKing delivers high-performance results in .30‑caliber platforms.
