The .7mm Weatherby Magnum is a powerful rifle cartridge supplied by Weatherby weapons in their Mark V rifles. The cartridge was one of the Weatherby company's initial cartridges. Roy Weatherby created it as part of the initial line of Weatherby cartridges in the early 1940s. The .7mm Weatherby Magnum cartridge, like the .257 Weatherby Magnum and the .270 Weatherby Magnum, is based on the.300 Holland & Holland Magnum case, necked down to .284 caliber, with a double radius neck and a straight taper. It is shortened to be fed from a standard-length action, as the.257 Weatherby Magnum and the .270 Weatherby Magnum are.
The .7mm Weatherby Magnum did not receive much attention until the early 1950s when Weatherby guns were more widely accessible. The more popular .7mm Remington Magnum, which has similar ballistics to the .7mm Weatherby Magnum, was released in 1962. Despite the fact that the .7mm Weatherby Magnum was launched 18 years earlier, it has a modest advantage over the more popular .7mm Remington Magnum in terms of ballistics due to the case design.
The .7mm Weatherby Magnum cartridge is ideal for hunting medium to large-sized animals including mule deer, wapiti, and moose. However, with properly designed bullets, the .7mm Weatherby Magnum may be utilized to hunt bigger wildlife such as great bears and American bison. It is also quite beneficial while hunting plains wildlife in Africa and Australia. It is an ultra-high velocity cartridge that provides around 300-400 fps greater velocity with lighter bullets than the more common 30-06 Springfield, which is considered to be rather fast. It's natural to cringe in anticipation of the considerable recoil.
