Sig Sauer
The Sig Sauer Marksman Hunter 300 Win Mag ammunition brings precision and reliability to medium-game hunting and long-range field shooting. Built around Sierra GameKing projectiles, this 165-grain load delivers the accuracy hunters demand when it counts most—combining competition-level precision with practical stopping power in a caliber proven for deer, elk, and similar-sized game out to extended distances.
Sig's precision-loading process ensures consistency shot to shot, while the boat-tail bullet design minimizes drag for a flatter trajectory and reduced wind drift. That matters when you're threading a shot through timber or across a canyon. The thick jacket and skived nose design work together to deliver controlled expansion on game, balancing penetration with the energy transfer that makes for clean, ethical harvests. With a muzzle velocity of 3,120 fps and 3,566 ft-lbs of energy from a 24-inch test barrel, you're working with proven downrange performance in a factory round.
Each box contains 20 rounds, and Sig packages this ammunition in 10-box cases for those who shoot regularly or want to stock up for the season. Whether you're preparing for a September elk hunt, zeroing in at the range, or building confidence in a rifle you trust, Marksman Hunter ammunition bridges the gap between match-grade precision and field-ready practicality.
