Sierra 243 Cal 6mm 100gr Tipped GameKing

The Sierra 243 Cal 6mm 100gr Tipped GameKing is a premium bullet component designed for handloaders pursuing high-performance, long-range deer hunting and precision varmint work. As part of Sierra’s GameKing line, this .243‑inch, 100‑grain polymer‑tip Spitzer boat‑tail bullet delivers match‑grade consistency, aerodynamic superiority, and reliable expansion on medium game at extended distances.

Featuring a polymer tip bonded into a fine-meplat and a streamlined boat‑tail profile, the 243 Cal 6mm 100gr Tipped GameKing boasts a G1 ballistic coefficient of approximately 0.425. This high BC provides flatter trajectory, minimized wind drift, and fuller energy retention out to 500+ yards. The .243″ diameter ensures compatibility across popular cartridges such as .243 Winchester, 6mm Creedmoor, and 6mm-06, making it versatile for hunters and target shooters.

Manufactured to strict factory tolerances—100.0 grains weight, .243″ diameter, approximately 1.060″ overall length, and a sectional density of 0.215—the Sierra 243 Cal 6mm 100gr Tipped GameKing offers uniform jacket thickness, tight concentricity, and precise base alignment. The polymer tip initiates rapid yet controlled expansion, forming a hollow-point profile that preserves bullet mass for deep penetration on game like whitetail and antelope.

Optimized for barrels with twist rates of 1:9 to 1:10, this bullet component is capable of sub‑½‑MOA accuracy when loaded carefully in bolt-action and precision semi-auto rifles. Designed for velocities between 2,800 and 3,100 fps, the 243 Cal 6mm 100gr Tipped GameKing delivers reliable terminal performance while retaining match-grade external ballistics. The boat-tail design further supports supersonic stability and aerodynamic efficiency.

As a component bullet, the Sierra 243 Cal 6mm 100gr Tipped GameKing empowers handloaders with full control over powder type, primer choice, and seating depth—enabling tailored recoil management, trajectory optimization, and terminal effect. This bullet is not factory-loaded ammunition; it’s intended for users seeking precision, power, and flexibility in their handloaded rifle rounds.

In summary, the Sierra 243 Cal 6mm 100gr Tipped GameKing stands out as a top-tier polymer-tip GameKing bullet that balances aerodynamic efficiency, match-grade accuracy, and controlled expansion. Ideal for hunters and precision shooters alike, it delivers a dependable, long-range component-level solution for versatile applications in the field.
