Introduced in 1963, the 340 Weatherby was designed as a response to the 338 Winchester Mag. However, Roy took advantage of the longer case to pack in more powder for greater velocity. And, it shoots heavier 338 bullets at higher velocities as well a decidedly powerful combination. Ideally suited for animals the size of elk or larger, the 340 can also be used by deer hunters with lighter bullet weights.
