Sierra 284 Cal 7mm 165gr Tipped GameKing

The Sierra 284 Cal 7mm 165gr Tipped GameKing is a high-performance component bullet engineered for handloaders and hunters seeking aerodynamic efficiency, controlled expansion, and match-grade accuracy in 7mm-caliber rifles. Featuring a polymer-tip Spitzer boat-tail profile, this 165‑grain bullet blends long-range trajectory control with effective terminal performance—ideal for medium to large game.

Designed with a pointed Spitzer ogive, durable polymer tip, and boat-tail base, the 165gr Tipped GameKing achieves a G1 ballistic coefficient around 0.525. The elevated BC reduces drag and wind drift while preserving supersonic flight and flat shooting performance. Its .284″ diameter ensures compatibility with popular cartridges such as 7mm-08 Remington, 7mm Remington Magnum, and 7mm PRC.

Manufactured to Sierra’s strict component tolerances—165.0 grains weight, 0.284″ diameter, approximately 1.150″ overall length, and a sectional density near 0.294—the bullet maintains uniform jacket thickness, precise tip alignment, and consistent boat-tail geometry. These qualities support accurate seating, repeatable pressures, and tight group performance in tuned handloads.

Optimized for barrels with twist rates between 1:9 and 1:10, the Sierra 284 Cal 7mm 165gr Tipped GameKing performs best at velocities between 2,800 and 3,100 fps. Handloaders report precise shot placement, excellent wind resistance, and controlled transfer of energy to medium and large game—making this bullet a trusted choice for precision hunters and target shooters.

As a component bullet, the Sierra 284 Cal 7mm 165gr Tipped GameKing grants full reloader control over powder selection, primer choice, and seating depth—enabling tailored load development for trajectory, recoil moderation, and terminal effect. It is not factory-loaded ammunition but a premium polymer-tip Spitzer component built for custom long-range .284-caliber applications.
