Description
The HSM Game King line combines time-tested Sierra bullets with precisely calibrated powders and primers to give you factory ammunition that feels like it came out of a hand-loader's bench. Every component is matched to the GameKing bullet, resulting in the kind of consistency that matters when you're in the field.
180-Grain Sierra GameKing for Medium to Large Game
This load uses a 180-grain Sierra GameKing soft point with a boat-tail design, the weight that the .30-06 Springfield was practically made for. That 180-grain bullet strikes a real balance between power and velocity, generating enough energy for elk and moose while still maintaining a respectable trajectory for longer shots. You get deep penetration from the heavy bullet combined with solid expansion from the soft point construction. The boat-tail design helps flatten trajectory and keeps energy downrange where it matters.
Quality That Shows
What sets the Game King line apart is how much attention HSM pays to matching components. The powder, primer selection, and brass work together with that Sierra bullet in a way most factory ammo doesn't bother with. You'll notice tighter velocity spreads and more consistent shot placement than you might expect from a box of factory rounds. Sierra GameKing bullets have a solid reputation going back decades, and HSM builds on that foundation by refusing to cut corners on the ammunition surrounding them.
What to Expect in the Field
The 180-grain bullet delivers reliable performance across typical hunting ranges. Shot placement matters as it always does, but this load gives you the tools to do your part. Whether you're hunting whitetail at 200 yards or setting up on elk at distance, the combination of weight and velocity works for you. Brass cases mean you can reload if you want to extend the life of your ammunition, though most shooters will appreciate just loading the box and going.

Frequently Asked Questions
What game is the 180-grain bullet best suited for?
The 180-grain bullet is an excellent choice for elk, moose, and other large game animals, as well as a reliable option for deer at standard hunting ranges. The weight provides deep penetration and solid expansion, making it one of the most versatile bullet weights available for the .30-06. Most hunters find it performs well from close range out to 300 yards and beyond with proper shot placement.
How does HSM Game King ammo compare to handloads?
HSM matches each component of their Game King loads so carefully that the finished ammunition produces velocity spreads and consistency levels that rival quality handloads. The boat-tail Sierra GameKing bullet works in harmony with the powder and primer selection, which is why many hunters report tighter groups and more predictable ballistics than they expected from factory ammunition.

What muzzle velocity should I expect from this load?
The 180-grain Sierra GameKing load from HSM typically achieves velocities in the 2,700 to 2,800 feet per second range, which is the standard for this bullet weight in the .30-06. Velocity may vary slightly depending on your specific rifle and barrel length.
