HSM GameKing rifle ammunition in .300 WSM delivers factory-loaded reliability with hand-load precision. Built around Sierra's time-tested GameKing bullet design, this 150-grain soft point load is engineered for hunters pursuing medium to large game where controlled expansion and consistent accuracy matter. Each cartridge pairs a proven bullet with matched components optimized for real-world hunting performance—not the generic factory compromise you'll find in mass-market ammo.
The 150-grain weight in .300 WSM strikes a practical balance: enough velocity and energy for ethical hunting at distance, yet manageable recoil and powder efficiency compared to heavier loadings. Sierra GameKing bullets have built their reputation on reliable performance in the field, expanding predictably across a wide velocity range to put game down cleanly. HSM's component matching means you're getting ammunition that shoots like a handload—tight velocity spreads and group consistency—straight from a factory box of 20 rounds.
If you shoot a .300 WSM and want hunting ammo that won't require you to reach for a reloading press, GameKing is a solid choice. It's the kind of ammunition that works equally well sighted in on a rifle you're confident in, whether you're hunting from a stand, glassing hillsides, or working through thick timber. The 20-round pack keeps your investment reasonable while giving you a proven load to rely on.

Each box contains 20 rounds of finished .300 WSM ammunition loaded with 150-grain Sierra GameKing soft point bullets.
HSM GameKing ammunition is designed and marketed as a hunting load. For extended range work and practice, you may find more economical options suitable.
