Description
.458 Winchester Magnum 450 Grain Barnes TSX )Triple Shock)- The .458 Winchester Magnum is a belted, straight-taper cased, Big Five game rifle cartridge. It was introduced commercially in 1956 by Winchester and first chambered in the Winchester Model 70 African rifle.[3] It was designed to compete against the .450 Nitro Express and the .470 Nitro Express cartridges used in big bore British double rifles. The .458 Winchester Magnum remains one of the most popular large game cartridges, and most major ammunition manufacturers offer a selection of .458 ammunition.
The .458 Winchester Magnum was designed for hunting dangerous game animals by emulating the performance of powerful English double rifle cartridges in a bolt-action rifle. The use of a bolt-action rifle offered hunters a cheaper alternative to the big-bore double rifle, and ammunition could be manufactured using available tooling. The .458 Winchester Magnum soon became a success as dangerous game hunters adopted the cartridge. Soon game wardens, wildlife managers, and professional hunters switched to the .458 Winchester Magnum as their duty rifle. The cartridge would become the standard African dangerous game cartridge in short order. The .458 Winchester Magnum’s case was based on a .375 H&H case shortened to 2.5 in (63.5 mm) and renecked (to reduce taper) to accept a .458 in (11.63 mm) bullet. The cartridge remains the largest of the standard length magnum cartridge family released by Winchester, which includes the somewhat obsolete .264 Winchester Magnum and the popular .338 Winchester Magnum.
The .458 Winchester Magnum was designed for use against heavy thick skinned African game species such as elephant, rhinoceros and African Cape buffalo. While the .458 Winchester Magnum is considered over powered for North American game species, the cartridge has found use for the hunting of large bears such as the polar and Alaskan brown bear and American bison. A few guides in Alaska and Canada carry rifles chambered in this cartridge to provide a defense against these largest bear species for themselves and their clients. The number one cartridge of professional guides in Alaska for Great Bears is the .338 Winchester Magnum.
As almost all dangerous game hunting is conducted at short ranges with most shootings occurring well within a distance of 60 yd (55 m), the .458 was not designed as a long range hunting cartridge. Its effective hunting range against large dangerous game is considered less than 110 yds.
