HSM Ammo 300 Weatherby Magnum 150gr Sierra GameKing SBT 20 Rd - Box or Case

The HSM Ammo 300 Weatherby Magnum 150gr Sierra GameKing is a hunting rifle load built around the proven Spitzer Boat Tail (SBT) projectile, loaded in reloadable brass cases and offered in 20-round boxes for hunters running one of the most powerful standard production cartridges on the market.

Each round uses a 150-grain Sierra GameKing SBT - a jacketed soft-point boat-tail design favored for its consistent expansion, retained velocity, and flat trajectory downrange. The boattail base helps stabilize the bullet in flight, while the soft-point tip mushrooms on impact for clean, ethical kills on deer, antelope, and similar big-game animals.

At the muzzle this load drives the 150-grain bullet at 3425 fps and delivers 3908 ft lbs of energy - serious performance that takes full advantage of the .300 Weatherby Magnum's reputation as a flat-shooting, high-energy hunting round. The reloadable brass case also makes this a practical choice for handloaders looking to fine-tune their own .300 Wby Mag loads once the factory ammunition is gone.
