Historical Notes:
The .240 Weatherby was added to round out the Weatherby
proprietary magnum line, in 1968. It differs from other 6mms in
having a belted case with somewhat greater powder capacity. It is
very similar to the .240 Belted Rimless Nitro-Express introduced by
Holland & Holland around 1923. Thus far, it is available only in the
Weatherby Mark V bolt-action rifle or through custom gunsmiths. It
is an excellent cartridge and will push the 100-grain 6mm bullet
with about 200 fps greater muzzle velocity than the 6mm
Remington, and around 300 fps faster than the .243 Winchester.
However, a considerable portion of this ballistic advantage results
from increased barrel length and loading pressure. It is important to
allow plenty of barrel cooling time with this and all high-intensity
cartridges. The principal detraction regarding the .240 Weatherby
Magnum is that ammunition is expensive and difficult to find. The
.240 case has about the same capacity as the .30-06, and rim
diameter is also the same.

General Comments:
The .240 Weatherby is among the most powerful of the 6mm
cartridges. It represents the maximum performance that one can
squeeze through a 6mm tube with modern powders. The .244 H&H
Belted Rimless Magnum, based on necking-down the .375 H&H
Magnum case, will hold more powder, but doesn’t produce any
improvement in ballistics. The late Roy Weatherby built a successful
proprietary gun business on the basis of a good product plus the
all-important element of ballistic one-upmanship. The Weatherby
magnum cartridges have traditionally offered higher velocity and
energy than their standard factory counterparts. The .240 was born
of this same tradition. Of course, Remington, Winchester, Norma,
etc., have their own magnum lines in various calibers, and
Winchester offered the .300 and .375 H&H Magnums before World
War II. However, Roy Weatherby was the first to really popularize
this British innovation in the United States, convincing the American
shooters that it was something they truly needed.
