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 was designed to emulate the performance of the .450 Nitro Express in a standard-length bolt-action rifle. However, it soon became apparent that the .458 Winchester Magnum was not performing as anticipated. Several factors contributing to its less than stellar performance in Africa: clumping of its compressed powder charge and use in 20–22 in (510–560 mm) barrel rifles.

Jack Lott, a big-game hunter and writer from the US, had an adverse encounter with a Cape buffalo in Mozambique in 1959 in which he sustained injuries. He had been hunting with the then new .458 Winchester Magnum.^[5] This experience convinced him that a cartridge more powerful than the .458 Winchester Magnum was required when hunting dangerous game in Africa. After the encounter he began a search for a big-bore cartridge which would suit his needs perfectly.

Not finding a cartridge that would fit his needs, he designed a cartridge which he felt would meet his requirements in a dangerous-game cartridge. Jack Lott’s original drawings of the cartridge were done on a napkin at a diner. The first cases for the new rifle cartridge were fireformed from .375 H&H Magnum brass into a chamber by using .458 caliber (11.6 mm) bullets which had their bases re-sized .375-inch (9.5 mm) so as to fit in the mouth of the .375 H&H Magnum. This method of fireforming left the newly formed cases slightly shorter than the parent cases. The resulting cartridge is named the .458 Lott in his honor.
