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.

Designed to replace the .375 Weatherby Magnum, deep penetration and bone smashing power are the calling cards of the .378. Its massive case holds so much powder that Federal designed its super hot 215 primer to handle the load. Roy Weatherbys .378 delivers 34 percent more energy at the muzzle than the powerful .375 H&H Magnum. Since 1955, the .378 has become one of the worlds most popular cartridges for the largest of big game animals.
