Sierra 270 Cal 6.8mm 140gr Tipped GameKing

The Sierra 270 Cal 6.8mm 140gr Tipped GameKing is a premium bullet component for handloading, designed to deliver precision, controlled expansion, and superior long-range ballistic performance in medium to large game applications. Built on Sierra’s renowned GameKing line, this .277-inch, 140gr polymer-tip bullet combines a Spitzer boat-tail profile with a polymer tip for improved aerodynamics and consistent expansion.

Featuring a polymer tip and boat-tail configuration, the 270 Cal 6.8mm 140gr Tipped GameKing achieves a G1 ballistic coefficient of approximately 0.494. This high BC reduces wind drift and retains velocity, enabling flat trajectory and dependable terminal performance at ranges beyond 400 yards. The 0.277″ diameter matches standard .270 Winchester and 6.8mm barrels, ensuring compatibility with common hunting cartridges such as .270 Win, .280 Rem, 6.8 SPC, and 6.8 Creedmoor.

Constructed to precise factory specifications—140.0 grains weight, 0.277″ diameter, 0.984″ OAL, and 0.232 sectional density—the Sierra 270 Cal 6.8mm 140gr Tipped GameKing provides consistent accuracy and reliable expansion. The bullet’s jacket features controlled thickness and a thick rear portion to allow deep penetration, making it suitable for elk, deer, and big game. The polymer tip initiates controlled expansion, transitioning the bullet into a fine hollow-point construction that preserves mass deep into vital zones.

Designed with hunters in mind, this bullet expands reliably at velocities between 2,600 and 2,900 fps—common in .270 Win and 6.8 Creedmoor environments. The 270 Cal 6.8mm 140gr Tipped GameKing maintains tight accuracy capable of sub-MOA performance in bolt-action rifles with twist rates of 1:10 to 1:11. Community feedback highlights its effective terminal performance in deer-sized game with deep skeletal penetration and clean exit wounds.

As a component bullet, the Sierra 270 Cal 6.8mm 140gr Tipped GameKing provides reloaders full control over powder charge, primer choice, and seating depth to tailor trajectory, recoil, and terminal impact. Typical applications include big-game hunting in open terrain, precision-long-range whitetail work, and mountain hunting where ballistic efficiency and reliable performance matter most. This bullet is not factory-loaded ammunition; it is intended for handloaders seeking match-grade components.

In summary, the Sierra 270 Cal 6.8mm 140gr Tipped GameKing is a top-tier Spitzer boat-tail polymer-tip bullet ideal for hunters requiring deep penetration, high accuracy, and ballistic stability. With its strong BC, controlled expansion, and component flexibility, this GameKing bullet stands out as a reliable match-grade choice for big-game hunters and precision shooters.
