Hornady American Whitetail Ammunition 300 Winchester Magnum 150 Grain Interlock Spire Point 20RD

Hornady American Whitetail ammunition in 300 Winchester Magnum is purpose-built for hunters who demand reliable, ethical kills on deer and elk. This 150-grain load pairs the proven 300 Win Mag's flat trajectory and energy retention with Hornady's InterLock bullet technology—a combination that's been trusted by serious whitetail hunters for decades. Load a box of 20 rounds and head to the field with the confidence that comes from ammunition engineered specifically for medium to large game.

The InterLock bullet is the heart of what makes American Whitetail work. Its raised ring is mechanically locked into the bullet's core, preventing jacket and core separation during expansion. This engineering keeps mass and energy downrange where it counts, delivering the controlled expansion and penetration that ethical hunting demands. The exposed lead tip initiates consistent expansion across a wide range of impact velocities—whether you're shooting from your truck at 100 yards or making a longer stalk.

Hornady loads American Whitetail to conventional velocities optimized for modern rifle platforms, including semi-autos. Each cartridge combines quality brass, dependable primers, and powders that have been pressure-tested and matched to the load for shot-to-shot consistency. That consistency translates into predictable zero-hold and tighter groups in the field—exactly what you need when your chance at a good buck is on the line.
