The .458 Lott is a .458 caliber rifle cartridge designed to hunt large, thick-skinned dangerous game animals in Africa. It based on the full length .375 H&H Magnum case blown out and shortened to 2.800 inches (71.1 mm).

The .458 Winchester Magnum was designed in 1956 and was an immediate commercial success. It was a more economical alternative to the English double rifles that were considered the standard rifle type for dangerous game hunting in Africa. The .458 Winchester Magnum designed to emulate the performance of the .450 Nitro Express in a standard-length bolt-action rifle.
