Description
HSM has put together a solid hunting load with their Game King lineup by pairing Sierra's time-tested GameKing bullet with components that are matched together to deliver both accuracy and consistent performance. This particular load uses a 160-grain Sierra GameKing spitzer boat-tail bullet in a brass case with a muzzle velocity of 2786 fps and 2800 foot-pounds of muzzle energy. The result feels like shooting handloads out of a factory box.
GameKing Bullet Performance
The 160-grain Sierra GameKing SBT is designed specifically for long-range big game hunting. The boat-tail design reduces drag and helps maintain velocity downrange, which means flatter trajectory and better energy retention at distance. The bullet features a hollow point cavity with a closed tip opening that controls initial expansion, while four skives cut into the jacket ensure even mushrooming. You get penetration that hunters count on without excessive fragmentation, making this a solid choice for elk, deer, and other medium to large game where shot placement and follow-through matter.
Why the Precision Matching Matters
What sets HSM's Game King apart from standard hunting ammo is the attention paid to component pairing. Each caliber gets its own load development work rather than pulling generic recipes off the shelf. The powder charge, primer selection, and seating depth are all dialed in specifically for the 160-grain GameKing bullet. That attention to detail translates to tighter group sizes at the range and more consistent ballistics in the field. Many shooters report getting accuracy levels that compare favorably to carefully assembled handloads, but without the time commitment.
20 Rounds Per Box
This ammo ships 20 rounds per box in standard brass cases that are reloadable if you want to stretch your investment further. The 7mm Remington Magnum itself is known as one of the more balanced magnum cartridges, offering plenty of power for long-range hunting without punishing recoil that ruins shot placement.

Frequently Asked Questions
What game is the 160-grain GameKing suitable for?
The 160-grain Sierra GameKing SBT works well on elk, deer, bear, and moose-sized game. It's particularly effective for hunters who want heavier, tougher bullet construction for larger animals while maintaining good long-range ballistics typical of 7mm Rem Mag loads.
How does HSM's component matching improve accuracy?
HSM precisely matches powder charges, primers, and seating depths specifically for each bullet weight and type in the Game King line. This level of consistency across each round mimics the care that goes into handloading, which is why many shooters report accuracy that rivals their own custom loads.
Can I reload the brass cases?
Yes, the ammunition ships with reloadable brass cases. Collectors typically resize, reprime, and reload these cases for additional shooting. This can help stretch your ammunition budget if you reload your own rounds.
What makes the boat-tail design important for hunting?
The boat-tail reduces drag and helps the bullet maintain velocity and energy downrange. This means a flatter trajectory, better wind-bucking performance, and retained energy at longer hunting distances where clean kills matter most.
