.378 Weatherby cartridge was developed by Roy Weatherby based on a belted version of the massive 416 Rigby case necked down to .375”. This was introduced as a Weatherby proprietary cartridge in 1953. During the 1960’s, U.S gun writer Elmer Keith and Bob Thompson created the wildcat .338-378 by shortening the .378 case slightly and necking it down to .338”.

The .338-378 Weatherby Magnum is appropriate for hunting all game animals on the North American, European and Asian continents. In Africa the 338-378 Weatherby Magnum is appropriate for taking medium and large game.

The .338-378 Weatherby currently maintains a modest following for hunting big game at long ranges. The Lapua and its tactical appeal have certainly stolen some of its thunder but there are still a good many hunters who loyally stand by the Weatherby.
