HSM Ammo .338 Winchester Magnum 215gr Sierra GameKing SBT 20rd Rifle Ammo - Box or Case

The HSM .338 Winchester Magnum load is built around the legendary Sierra GameKing Spitzer Boat Tail (SBT) projectile, a 215-grain jacketed soft point designed for deep penetration and reliable expansion on large North American big game. Loaded in reloadable brass cases, this round is tailored for elk, moose, bear, and other tough game where the magnum-class energy of the .338 Win Mag really shines.

Each 20-round box delivers consistent premium-grade ammunition suitable for hunting trips or load development. The Sierra GameKing SBT features a boat-tail design that improves ballistic coefficient and downrange accuracy, while the exposed soft-point tip promotes controlled expansion on impact. Like all HSM centerfire rifle ammunition, this load is built on reloadable brass loaded to standard .338 Winchester Magnum specifications.

This New production ammunition is the same load HSM boxes under product code 338MAG-15-N, providing a trustworthy factory load for the long-action .338 Win Mag rifle platform.
