Weatherby Select 340 Weatherby Magnum 250 Grain Hornady InterLock Spire Point Ammunition - 20 Rounds

The Weatherby Select 340 Weatherby Magnum 250 Grain Hornady InterLock Spire Point Ammunition delivers the velocity and power hunters expect from Roy Weatherby's legendary magnum cartridge. Born in 1963, the 340 Weatherby was engineered to outperform the 338 Winchester Magnum by leveraging a longer case capacity for additional powder charge—and it shows. This 250-grain load launches at 2685 fps and generates 4002 ft-lbs of muzzle energy, making it a serious choice for large-game hunting where margin for error is slim.

Loaded with Hornady's proven InterLock bullet, this ammunition combines reliable expansion with deep penetration. The InterLock design mechanically locks the core to the jacket, resisting separation during impact and ensuring consistent, lethal performance. At this velocity and energy level, the 340 Weatherby is naturally suited to elk-sized game and larger, though hunters pursuing deer with the cartridge often select lighter bullet weights.

If you own a 340 Weatherby rifle and hunt big country, this factory ammunition delivers the ballistics and consistency you've come to expect from Weatherby Select. Each box contains 20 rounds, ready to go. Stock it before your next hunt.
