Description
The 6mm Remington doesn't get the attention it deserves, but anyone who owns one knows it's a flat-shooting, low-recoil cartridge that handles medium-sized game with real authority. HSM GameKing ammo brings together proven components specifically matched to maximize what this old round was designed to do.
HSM matched each component in this load to the Sierra GameKing bullet rather than just throwing together standard parts. The boat-tail design helps the 100-grain GameKing maintain velocity and energy at distance, which is where the 6mm Rem really shines. You get the accuracy potential of precisely engineered factory ammo without the guesswork that comes with mixing different manufacturers' powders, primers, and components. The result shoots so cleanly that people sometimes compare HSM Game King loads to handloads.
HSM GameKing For Deer and Antelope Hunting
The 100-grain GameKing is the classic choice for 6mm Rem hunting. At 300 yards, this load retains around 1,280 foot-pounds of energy, which is plenty for ethical kills when you place your shot well. The bullet's soft-point design provides reliable expansion while the boat-tail profile helps it cut through wind and maintain trajectory at extended ranges. Whether you're hunting open country where you need to dial holdover or working moderate distances through brush, this round performs across the spectrum.
Features Built for Long-Range Performance
Boxer primers in reloadable brass cases mean you can reload when you're ready, or just shoot them as factory ammo and not think twice. The ammunition is non-corrosive, so there's no stress about barrel fouling. Each box contains 20 rounds loaded to consistent velocities, so what you see on the range is what you'll get in the field.

Frequently Asked Questions
How does the 6mm Rem compare to the .243 Winchester?
The 6mm Rem has a slight ballistic advantage over the .243 Win, especially with 100-grain bullets. You'll see roughly 3-4 inches less bullet drop at 400 yards, which matters in open-country hunting where precise holdover calculation is necessary. Both handle medium game well, but the 6mm Rem delivers a bit more velocity with the heavier bullets.
Is the GameKing bullet good for longer-range hunting?
Yes. The boat-tail design and soft-point construction make the GameKing reliable at extended ranges. The 100-grain variant is the classic choice for 6mm Rem at moderate to longer distances on deer and antelope. It's praised for consistent accuracy and reliable expansion.
Can I reload this HSM ammo?
Yes, the brass is boxer-primed and reloadable. The cases are non-corrosive, so they won't have damage from firing. Once you've shot through a batch, you can reload the brass according to published load data for the 6mm Rem.
What game is this HSM GameKing load suitable for?
The 100-grain GameKing in 6mm Rem is designed for deer and antelope-sized game. At 300 yards, it retains roughly 1,280 foot-pounds of energy, which is adequate for ethical kills with well-placed shots. It's not intended for larger game like elk.
