The Sierra GameKing .375 caliber 300 grain rifle bullet is a purpose-built magnum round for hunters pursuing heavy game at distance. Built on Sierra's reputation for precision and consistency, this soft-point (SBT) bullet combines a robust construction with ballistic efficiency—making it a smart choice if you're loading for a .375 H&H Magnum, .378 Weatherby Magnum, or similar large-bore cartridge intended for elk, moose, bear, or African dangerous game.
What sets the GameKing apart is its engineering foundation: a thick-walled copper jacket formed through Sierra's four-station draw process to exacting tolerances, paired with a hard 3% antimony lead alloy core. That combination yields a bullet designed to expand reliably across a range of velocities and impact angles while maintaining structural integrity for deep, straight-line penetration. The classic SBT (spitzer boat-tail) profile delivers an excellent ballistic coefficient, so your downrange energy and trajectory stay consistent from 100 yards to well beyond—critical when you're making a single, ethical shot on dangerous game.
Reloaders and hunters report exceptional accuracy with the GameKing; tight 100-yard groups are well within reach when brass, powder, and primers are sorted. Each box ships 50 bullets, giving you a full component set for serious handload development or season prep. If you're serious about long-range heavy-game hunting and demand a bullet that won't let you down, the Sierra GameKing earns its place on the bench.

The Sierra GameKing 300 gr .375 is designed especially for the .375 H&H Magnum and .378 Weatherby Magnum, though it may be suitable for other large-bore .375-caliber cartridges. Always verify compatibility with your specific rifle and load data before reloading.
Yes. The spitzer boat-tail profile and high ballistic coefficient make this bullet well-suited for extended-range shooting. Sierra reports consistent downrange performance across a variety of hunting distances and impact scenarios.
The GameKing is designed for heavy North American game (elk, moose, bear) and heavy thin-skinned African game. The bullet's expansion characteristics and penetration performance are optimized for these large-bodied animals.
Each box contains 50 bullets, giving you a complete set for reloading or handload development.
