Weatherby ammunition remains true to the concept Roy Weatherby developed in the 1940s, the faster a bullet traveled, the better. The flatter it would shoot, the less it would drop, the harder it would hit, the better its terminal performance. At the same time, our ammunition also takes advantage of the latest in controlled expansion bullets which are capable of harnessing the higher velocities to create a cartridge that provides the ultimate in penetration, large wound channels and more one shot kills.

Another Weatherby wildcat, the .338-378 was first introduced in the 1960s. This is good cartridge for longrange, big game hunting. Delivers more than 5,000 foot pounds of energy at the muzzle with a .338 sized bullet. Extremely powerful and flat shooting. Based upon the .378 case, necked down to .338. Reintroduced as a Weatherby production cartridge in 1998. The TSX has gained worldwide recognition as one of the deadliest, most dependable bullets you can buy. Try these all-copper bullets and realize the added benefits of improved accuracy, reduced barrel fouling and increased velocity.
