Sierra 7.62mm 30 Cal 125gr Tipped GameKing

The Sierra 7.62mm 30 Cal 125gr Tipped GameKing is a high-performance bullet component designed for hunters and handloaders seeking premium terminal performance and accuracy. Built to match-grade tolerances, this polymer‑tipped bullet delivers explosive expansion and reliable weight retention upon impact. It is a component bullet—not factory‑loaded ammunition—intended for tailored handload development in calibers such as .308 Winchester, 7.62×51 NATO, and 30-06 Springfield.

This 125gr Tipped GameKing features a streamlined Spitzer boat-tail design topped with Sierra’s acetal-resin tip, facilitating enhanced ballistic coefficient and elevated downrange stability. The sharp polymer tip ensures clean bullet flight and initiates rapid expansion on game. The G1 ballistic coefficient is approximately 0.397, and the sectional density registers near 0.230—providing flat trajectories, superior energy retention, and minimal wind drift for mid- to long-range shots.

Optimized for bolt-action and magazine-fed rifles, the 7.62mm 30 Cal 125gr Tipped GameKing performs reliably in barrels with a 1:10″ twist or faster. The bullet’s overall length supports standard magazine stack without sacrificing ballistic form, making it suitable for hunting and precision shooting. Consistent manufacturing ensures weight variances within 0.5 gr and uniform base-to-ogive dimensions, promoting repeatable accuracy and load consistency.

The acetal-resin tip offers two key advantages: it enhances aerodynamics for flatter trajectory and improves feeding in semi-auto platforms. Handloaders using the 7.62mm 30 Cal 125gr Tipped GameKing often report sub-MOA groups at 100 yd and effective terminal performance from 200 to 600 yd. Its boat-tail geometry maintains energy and velocity stability, ensuring controlled expansion across hunting ranges.

While the primary mission of this bullet component is hunting, its match-grade construction allows it to double as a precision target projectile. The sharp tip yields consistent initial impact, generating predictable expansion on whitetail deer, pronghorn, and similar medium-size game. It does not deliver the explosive fragmentation of lighter varmint bullets, but instead balances deep penetration with reliable bullet integrity.

Available in 100‑count boxes, the Sierra 7.62mm 30 Cal 125gr Tipped GameKing offers handloaders a premium option for those seeking accurate, consistent, and effective performance. Its combination of polymer tip, boat-tail design, and exacting tolerances makes it a top-tier component for serious hunters and precision shooters requiring dependable results.
