Sierra 7.62mm 30 Cal 165gr HPBT GameKing

The Sierra 7.62mm 30 Cal 165gr HPBT GameKing is a high-performance component bullet crafted for hunters and handloaders seeking a versatile midweight .30-caliber option that balances accuracy, penetration, and aerodynamic efficiency. Part of Sierra’s GameKing series, this .308-inch, 165-grain hollow-point boat-tail bullet is engineered to retain accuracy and terminal effectiveness at medium to long ranges.

Designed with a streamlined hollow point and tapered boat-tail base, the 7.62mm 30 Cal 165gr HPBT GameKing achieves a G1 ballistic coefficient of approximately 0.363. Its aerodynamic profile reduces drag and wind drift, ensuring flatter trajectories and strong energy retention beyond 800 yards. The .308″ diameter ensures compatibility with popular cartridges including .308 Winchester, 7.62×51 NATO, and .30-06 Springfield.

Manufactured to stringent specifications—165.0 grains weight, 0.308″ diameter, around 1.17″ overall length, and a sectional density of approximately 0.248—the bullet exhibits uniform jacket thickness, precise hollow-point geometry, and tight concentricity. Its profile supports match-style accuracy in bolt-action and precision semi-auto rifles, making it a preferred choice in hunting and target-practice applications.

As a midweight HPBT GameKing bullet, this component offers reliable expansion and deep penetration on medium game such as deer, antelope, and hogs. It is slightly harder in construction than the traditional 165-grain SBT version, delivering enhanced terminal performance at velocities above 2,500 fps. Hunters will appreciate its balance of accuracy and penetration without the risk of mushrooming too rapidly.

This bullet is optimized for twist-rate barrels of 1:10 to 1:12 and delivers sub‑MOA precision when loaded carefully. It is designed for handloaders who require component-level customization—allowing selection of primer, powder, and seating depth to tailor recoil, trajectory, and terminal performance. It is not loaded ammunition and must be assembled into complete cartridges.

In summary, the Sierra 7.62mm 30 Cal 165gr HPBT GameKing is a versatile, match-accurate hollow-point boat-tail bullet that combines aerodynamic efficiency, reliable expansion, and penetration. Ideal for handloaders and hunters seeking a premium midweight .30-caliber component, this GameKing variant delivers consistent, high-performance results across field and range applications.
