.458 Lott 500 Grain Nosler Partition- The .458 Lott is a .458 caliber belted hunting cartridge designed as a replacement for the less powerful .458 Winchester Magnum. It is based on the full length .375 H&H Magnum blown out and shortened to 2.800 inches. The cartridge is designed for the purpose of hunting African dangerous game.
The .458 Lott was designed in response to perceived inadequacies and problems encountered with the .458 Winchester Magnum. The cartridge provides a distinct step up in performance over the .458 Winchester Magnum. Jack Lott, a big-game hunter and writer, had an adverse encounter in Mozambique in 1959 with an African Cape buffalo in which he sustained injuries. He had been hunting with the then new .458 Winchester Magnum. This experience convinced him that a more powerful cartridge than the .458 Winchester Magnum was required when hunting dangerous game. After the encounter, he began a search for a big-bore cartridge which would suit his needs perfectly. The objective behind the design of the .458 Lott was to provide a greater case capacity over the .458 Winchester Magnum, so as to provide better performance and less compression of the powder charge. The .458 Lott achieved both these objectives by its lengthened cartridge. Furthermore, as the Lott cartridge is in essence a lengthened .458 Winchester Magnum, converting a .458 Winchester Magnum to .458 Lott involves in many cases a simple re-boring of the chamber and if required, a lengthening of the magazine.
The .458 Lott was designed to be an African dangerous game rifle cartridge particularly for use against heavy, thick skinned dangerous game such as elephant, Cape buffalo and rhinoceros. It is considered an ideal cartridge for hunting African dangerous game and is capable of taking game from elephant to the duiker. Acceptable bullet weights for the .458 Lott range from 300-to-600-grain. The range of available bullets provides the flexibility to customize loads for specific game species.

Partition Bullets feature a fully tapered jacket that ruptures instantly at the thin jacket mouth, yet the gradual thickening along the bullet’s axis controls expansion and curls the jacket uniformly outward at high or low velocities. Nosler’s integral Partition supports the expanded mushroom and retains the rear lead alloy core. The enclosed rear core retains more than half the original bullet weight for deep penetration. The special crimp locks in the rear core section, adding strength to resist deformation under the pressure of heavy magnums.
