Introduced in 1968, the 240 Weatherby Magnum was Roy Weatherby's final addition to his line of Weatherby Magnum cartridges. The case is belted and uses the signature Weatherby "double Venturi" shoulder, but the rim diameter (.473-inch) and case length (2.5 inches) are the same as the .30-06 family. The 240 Weatherby is the fastest commercial 6mm cartridge, propelling a 100-grain bullet at almost 3400 feet per second in Weatherby factory ammunition. Extremely flat-shooting, it is a fine cartridge for deer and pronghorn out to at least 300 yards, and with lighter bullets is an excellent long-range varmint cartridge. Weatherby has been the only ammunition manufacturer, and other than custom rifles only Weatherby has chambered rifles to the 240.
