Description
Sierra GameKing bullets have a long track record for hunting performance, and HSM has built its entire Game King line around them. What makes this ammunition stand out is the meticulous component matching. HSM doesn't just load any powders or primers with Sierra bullets. Instead, each caliber gets its own tuned load, with components specifically selected to maximize accuracy and terminal performance from that particular bullet.
HSM Game King 6.5 Creedmoor Ballistics and Handling
This 140-grain load launches at 2714 feet per second, generating 2290 foot-pounds of muzzle energy. That's solid downrange performance for 6.5 Creedmoor, giving you the flat trajectory and velocity retention you want when hunting at distance. The spitzer boat tail design reduces drag and enhances aerodynamic stability, which means tighter groups and more consistent impact even when conditions aren't perfect.
Why the Boat Tail Design Works
The boat tail configuration isn't just for target shooters anymore. The aerodynamic advantage means less wind deflection and better energy retention downrange compared to flat-base bullets. For hunting, this translates to more consistent terminal performance across varying ranges and conditions. When you're counting on making an ethical shot, those ballistic advantages matter.
Game King for Medium and Large Game
The soft point design of the GameKing bullet delivers controlled expansion and deep penetration on everything from whitetail and mule deer to elk and larger game. The bullet's construction allows it to hold together and penetrate deep, not just blow up on the surface. Each box contains 20 rounds of reloadable brass, so once you've used them, the cases have value for hand loaders.

The soft point design and penetration characteristics make it a solid choice for hunting situations where you need both expansion and deep penetration.
How does the boat tail design affect accuracy at long range?
The spitzer boat tail reduces aerodynamic drag and improves stability in flight, which means your bullets maintain velocity better and are less affected by wind. For hunting, this translates to more consistent ballistic performance whether you're shooting at 100 yards or stretching it out to 300.
