.425 Express (Cartridges of the World)

.425 Express (Cartridges of the World)
Warning! Notes: The 425 Express fills a gap in the medium-bore cartridge lineup between the 375 Holland & Holland Magnum and the 458 Winchester Magnum. This cartridge fits standard-length bolt actions such as the Winchester Model 70, 1917 Enfield, Mauser 98 or other similar-length actions. This cartridge uses either a 350-grain or a 400-grain bullet and has proven very effective on heavy African game. It is overpowered for most North American hunting, but would provide a margin of safety if going after brown bears in the far North. Col. Charles Askins used the 425 Express very successfully on buffalo in Australia. (Cartridges of the World 10th Edition)
