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.

Weatherby has also expanded their factory loads including Nosler Ballistic-tip and Barnes TSX bullets complementing the powerful cartridge.Weatherby, Inc. , Rifles, Shotguns, Ammunition, Accessories

This cartridge is powerful enough for even the largest North American game and is suitable for most African game as well.[
