338-378 WEATHERBY

The 338-378 Weatherby Magnum is based on Elmer Keith and Bob Thomson’s 338-378 KT wildcat cartridge, which itself was based on the 378 Wby Mag. Introduced in 1998, The 338-378 Wby Mag’s larger case and higher muzzle velocity than the 338 Lapua Magnum make it a definitive choice for long-distance shooting and elk hunting. Available from Weatherby loaded with 225 grain, 250 grain or 262 grain projectiles.
