Factory-loaded hunting ammunition featuring Sierra GameKing bullets matched to .300 WSM specifications. Precision-engineered components deliver accuracy and reliable performance on medium to large game.
HSM has partnered with Sierra to bring you factory ammunition that rivals handloaded precision. This .300 WSM loading features the legendary Sierra GameKing bullet—a soft point design that has proven itself across decades of hunting applications.
Sierra GameKing bullets are engineered for controlled expansion and deep penetration. The soft point design initiates expansion on impact while the heavy jacket ensures the bullet stays together through bone and muscle, delivering energy where it counts.
Each component in this ammunition—powder charge, primer, and bullet—has been carefully selected and matched to maximize accuracy and ballistic performance in the .300 WSM. The result is factory ammunition with the consistency you'd expect from a careful handloader.
The .300 Winchester Short Magnum delivers magnum performance in a compact package. It's ideal for hunters who want velocity and power without excessive recoil, making it effective on elk, deer, and similar game at extended ranges.
Whether you're hunting in tight timber or open country, HSM GameKing ammunition delivers the accuracy and reliability serious hunters demand.
