458 Winchester Magnum

458_win_mag
The .458 Winchester Magnum is a belted, straight-taper cased rifle cartridge introduced in 1956 by Winchester. It was designed for big game hunting, particularly large and dangerous African game such as elephants, cape buffalo, and rhinos. The cartridge typically fires a .458-inch (11.6 mm) diameter bullet weighing between 350 and 500 grains, though the most common loading is a 500-grain bullet.
This cartridge was developed to provide magnum-level performance in a standard-length-action rifle, making it accessible and cost-effective compared to other big-bore cartridges of the time. The .458 Winchester Magnum can achieve muzzle velocities around 2,040 to 2,150 feet per second (620 to 655 m/s), delivering substantial stopping power and deep penetration necessary for hunting thick-skinned animals.
Its practical usage is largely limited to professional big game hunters and those participating in hunting safaris, and it stands as one of the most popular cartridges in its class among dangerous game hunters. Due to its significant recoil, it is not commonly used for hunting smaller game or for casual shooting.
