The .340 Weatherby Magnum rifle cartridge created by Roy Weatherby in response to the .338 Winchester Magnum[1]. The .340 Weatherby Magnum uses the same .338 in. diameter bullets as the .338 Winchester Magnum but it does so at greater velocity than its Winchester competition. Reloaders may have trouble matching the published Weatherby velocities as Weatherby factory ammunition is loaded to maximum specifications[2].
This cartridge is powerful enough for even the largest North American game and is suitable for most African game as well [3].
