Sierra GameKing 85gr Spitzer Boat Tail – Precision & Performance

At the heart of this load is the legendary Sierra GameKing bullet:

• Spitzer Boat Tail (SBT) design optimizes aerodynamics, delivering:

  • Flatter trajectories

  • Reduced wind drift

  • Better retained velocity and energy at extended ranges

• GameKing construction is engineered for hunting:

  • A lead core and tapered jacket designed for controlled expansion

  • Reliable penetration on medium-sized game

  • Excellent weight retention for consistent terminal performance

This combination makes the 85gr GameKing an outstanding choice for hunters who need their .243 Win to perform beyond the 200–300 yard mark while still providing effective on-target performance.

Ideal for Deer, Antelope & Medium Game

The .243 Win / 85 gr GameKing profile is a proven performer on:

• Whitetail and mule deer

• Pronghorn antelope

• Feral hogs

• Other thin-skinned medium game within appropriate distance

The high sectional density and efficient bullet design allow hunters to:

• Take broadside and slightly quartering shots with confidence (within ethical ranges)

• Enjoy minimal recoil, making it a great choice for youth, recoil-sensitive shooters, or those who value fast follow-up capability

Paired with a well-zeroed rifle, HSM’s Game King load transforms your .243 Win into a precision hunting tool.

Flat Trajectory & Long-Range Accuracy

The combination of the .243 Winchester’s inherent flat shooting characteristics and the 85 grain SBT’s high ballistic coefficient yields:

• Minimal drop over typical hunting distances

• Greater resistance to crosswinds, especially compared to flat-base or less aerodynamic bullets

• Consistent performance for long-range varminting and medium-game hunting

For hunters who like to stretch the legs of their .243—whether in open country, prairie, or clear-cut environments—this load helps keep your point of impact predictable and repeatable.
