Hornady American Whitetail Ammunition 300 Winchester Short Magnum (WSM) 165 Grain Interlock Spire Point 20RD
The Hornady American Whitetail Ammunition in 300 Winchester Short Magnum (WSM) is purpose-built for hunters pursuing deer and similar-sized game. This 165 grain load pairs Hornady's proven Interlock bullet with the efficient short-magnum case, delivering the velocity and terminal performance that made the .300 WSM popular among hunters who want magnum power in a slightly trimmer package. If you're running a .300 WSM bolt rifle and want factory ammunition you can trust to perform when it counts, this is ammunition built specifically with that mission in mind.
The Interlock bullet design—a Hornady hallmark—features a mechanical lock between the core and jacket that promotes consistent expansion and weight retention on impact. For whitetail hunting, this translates to reliable energy transfer and predictable performance across typical hunting ranges. The spire point profile supports the ballistics you expect from the .300 WSM platform. Each round is manufactured to Hornady's quality standards, and you get 20 cartridges per box.
American Whitetail is Hornady's dedicated hunting line, engineered for the scenarios hunters actually encounter in the field. If you've chambered a .300 WSM for hunting deer or black bear, this ammunition gives you a factory option that won't force you to handload or source specialty rounds.
