240 Weatherby Magnum:
The 240 Weatherby Magnum was introduced in 1968 as the twelfth Weatherby cartridge in their belted long range rifle cartridge line-up.
The 240 Weatherby cartridge case is unique in its design and is best described as a .30-06 cartridge case necked down to .243″ caliber and a belt added to the case.
The 240 Weatherby Magnum is one of the most powerful commercially available cartridges in .24″ caliber, able to send 85 grain bullets downrange at velocities of 3,500 fps. and 100 grain bullets in excess of 3,400 fps.
That makes it a great dual purpose cartridge for varmint and deer with the ability to dispatch of either one out to 400 yards quite quickly.
The 240 Weatherby Magnum is a moderate to heavy recoiling cartridge which is still comfortable enough for most anyone to shoot.
For anyone who lives and hunts in areas where a good dual purpose, flat trajectory cartridge is needed, the 240 Weatherby Magnum cartridge has a lot to offer with excellent ballistics.
