The Weatherby Select 300 Weatherby Magnum 180 Grain Hornady Interlock ammo is purpose-built for hunters who demand flat-shooting, hard-hitting performance on big game. This factory-loaded round pairs Weatherby's legendary 300 Weatherby Magnum cartridge with Hornady's proven Interlock bullet design—a combination engineered to deliver consistent accuracy and reliable expansion downrange. If you're running a rifle chambered in 300 Weatherby Magnum and want ammunition you can trust on elk, moose, or long-distance hunts, this is your go-to box.
The 300 Weatherby Magnum earned its reputation for a reason: it delivers serious velocity and energy with a relatively flat trajectory, making it an effective choice for hunters willing to handload or shoot factory ammo at moderate to long distances. Weatherby Select ammunition takes the guesswork out of reloading by offering consistent, quality-controlled rounds loaded to proven specifications. The 180-grain bullet weight sits in the sweet spot for the cartridge—heavy enough to carry energy and momentum, light enough to maintain velocity.
Hornady's Interlock bullet features a mechanical lock between the core and jacket, designed to promote controlled expansion and consistent performance on game animals. Each box contains 20 rounds, making it a practical choice for range sessions, load development reference, or stocking a hunting trip. This ammo is factory-fresh and ready to shoot—no reloading required.
