Description
HSM Game King ammunition represents what happens when a respected ammunition maker gets serious about hunting performance. Each load pairs Sierra's time-honored GameKing bullet with components specifically matched to maximize accuracy and terminal performance. The result is factory ammo that reads like a handload in terms of consistency and tuning.
The 150-grain Sierra GameKing spitzer boat-tail bullet excels at what it was designed for: medium game hunting from close range to moderate distance. The tapered jacket is engineered for controlled expansion that doesn't sacrifice penetration, while the boat-tail shape reduces drag to maintain velocity downrange. That matters when you're threading shots through thick cover or looking to extend your effective range beyond 200 yards.
Game King Ammunition Built for the 7mm-08
The 7mm-08 has earned its reputation as a versatile, low-recoil cartridge that punches well above its weight. HSM recognizes this and loads the Game King specifically for the platform, not as an afterthought to a larger magnum. The 150-grain weight splits the practical difference: heavier than some featherweight options but still fast enough to keep a flat trajectory and manageable recoil impulse. It's the go-to weight for deer and black bear across varied terrain, whether you're hunting tight timber or open ridges.
What You're Getting in the Box
These are loaded in boxer-primed brass that's reloadable for those who want to develop premium handloads later. Non-corrosive primers and clean-burning powder ensure reliability in the field and easier cleanup at the range. Twenty rounds per box means you'll have enough for practice, hunting prep, and a full season without overcommitting to a single load if you're still figuring out what your rifle prefers.

Frequently Asked Questions
What game can I hunt with HSM Game King 7mm-08 150gr ammunition?
The 150-grain Sierra GameKing is purpose-built for medium game including whitetail deer, mule deer, and black bear. It performs well from close range through moderate distances, making it versatile across different hunting scenarios. Proper shot placement is always key, but this weight and bullet design are ideal for the game most 7mm-08 hunters pursue.
Are these cases reloadable?
Yes. HSM Game King ammunition comes in boxer-primed brass that can be reloaded. After you shoot them, you can clean, reload, and use them again with your own components, which makes this a cost-effective choice for those who handload or plan to develop custom loads.
How does the 150gr GameKing perform at distance compared to lighter options?
The 150-grain GameKing maintains velocity downrange better than lighter bullets thanks to its higher ballistic coefficient. This translates to a flatter trajectory and better wind resistance out past 200 yards, though it still retains the manageable recoil the 7mm-08 is known for. It's a sweet spot for hunters who want range capability without sacrificing the cartridge's traditional advantages.
What makes HSM Game King different from other factory ammunition?
HSM matches each component specifically for the GameKing bullet and cartridge combination. This attention to consistency and tuning typically results in ammunition that groups as well as careful handloads, with reliable velocities and performance from box to box. You're getting purpose-designed ammunition, not a generic load slapped into cases.
