HSM's GameKing line pairs time-tested Sierra GameKing bullets with carefully selected components matched specifically for each caliber. This 338 Lapua load uses the 215-grain Spitzer Boat Tail design, a bullet known for its track record with hunters tackling elk, moose, and other large game at distance. You get 20 rounds per box, assembled in Montana with the kind of attention to detail that makes factory ammo feel like quality handloads.
This particular combination is built for flat-shooting, long-range work. The 215-grain GameKing carries one of the highest ballistic coefficients in Sierra's lineup at 0.517, which means it resists wind drift and holds velocity downrange better than lighter bullets. Fired from the 338 Lapua platform at 3138 fps, you're looking at nearly 4,700 ft-lbs of energy at the muzzle—the kind of authority that matters when your target is hundreds of yards away.
The Spitzer Boat Tail design isn't just for show. That tapered base reduces drag significantly compared to flat-base bullets, giving you a flatter trajectory and better energy retention at distance. The bullet itself uses an exposed lead tip and proven cup-and-core construction that expands reliably across a wide velocity range. It's a design that's been working since the 1970s, refined over decades in the field.
HSM controls every variable here. The brass is selected for consistency, the powder charge is precise, and the primer is matched to the load. That matching process is what separates these rounds from random factory loads. The result shoots like ammo that came off a careful handloader's bench, but you get factory reliability and consistency without the time investment.
HSM specifically matches each caliber's components to the GameKing bullet to maximize accuracy and consistency. The precision is so tight that many shooters say HSM Game Kings feel like handloads. Each cartridge is inspected and tested for consistent velocity and performance, which is why they deliver the kind of shot-to-shot consistency serious hunters depend on.
Absolutely. The 215-grain Sierra GameKing is one of the highest ballistic coefficient options in the GameKing lineup at 0.517, making it a genuine long-range hunting choice. Paired with the 338 Lapua's velocity and energy, it's well-suited for elk, moose, and large game at extended distances where wind drift and energy retention matter.
The GameKing is designed with a cup-and-core construction that expands reliably across a wide range of impact velocities while maintaining good penetration. The exposed lead tip initiates expansion, and the design provides consistent performance on large game without fragmenting unpredictably. Actual performance depends on impact velocity, shot placement, and game size.
Yes. HSM uses quality brass casings that are suitable for reloading. As with any reloading, you'll want to inspect cases for damage, manage neck tension properly, and follow published load data from reputable sources. The brass quality is one reason many handloaders appreciate factory ammo from HSM.
