Sierra 243 Cal 6mm 90gr Tipped GameKing

Sierra 243 Cal 6mm 90gr Tipped GameKing

The Sierra 243 Cal 6mm 90gr Tipped GameKing is a high-performance component bullet engineered for handloaders and hunters seeking aerodynamic efficiency, precise expansion, and match-grade accuracy in .243‑caliber rifles. Featuring a polymer-tip Spitzer boat-tail profile, this 90‑grain bullet blends long-range capability with effective terminal performance—ideal for varmint control and medium-game use.

Designed with a sleek Spitzer ogive, polymer tip, and tapered boat-tail base, the 90gr Tipped GameKing achieves a G1 ballistic coefficient of approximately 0.440. This elevated BC supports flatter trajectories, reduced wind drift, and sustained supersonic flight. Its .243″ diameter ensures compatibility with popular cartridges such as .243 Winchester, 6mm Creedmoor, and 6mm-06.

Manufactured to strict component tolerances—90.0 grains weight, 0.243″ diameter, approximately 1.010″ overall length, and a sectional density around 0.195—the bullet maintains uniform jacket thickness, precise tip alignment, and consistent boat-tail geometry. These qualities contribute to reliable seating behavior, repeatable pressure consistency, and sub‑MOA accuracy in tuned load development.

Optimized for rifles with twist rates between 1:9 and 1:10, the Sierra 243 Cal 6mm 90gr Tipped GameKing performs best at velocities between 2,900 and 3,200 fps. Handloaders report tight groups, excellent wind resistance, and controlled tip expansion on small game and predators—making it a trusted choice for precision hunters and target shooters.

As a component bullet, the Sierra 243 Cal 6mm 90gr Tipped GameKing allows full reloader control over powder, primer selection, 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 dedicated .243-caliber custom loads.
