Load data for caliber ".458 Lott"
The .458 Lott is a powerful rifle cartridge designed for big game hunting in Africa. It was developed by Jack Lott in the 1970s as an improvement over the .458 Winchester Magnum, which had a reputation for not always providing reliable penetration on large, thick-skinned game such as buffalo and elephant.

The .458 Lott uses a longer and more powerful case than the .458 Winchester Magnum, which allows it to achieve higher velocities and greater energy at longer ranges. It is capable of taking down the largest and most dangerous game animals, including elephant, rhinoceros, and Cape buffalo.

However, the .458 Lott generates significant recoil, which can make it challenging for some shooters to handle. It is typically used by experienced hunters and guides who have been properly trained in its use.

The Commission internationale permanente pour l'épreuve des armes à feu portatives ("Permanent International Commission for the Proof of Small Arms" – commonly abbreviated as C.I.P.) is an international organisation which sets standards for safety testing of firearms. (The word portatives ("portable") in the name refers to the fact the C.I.P. tests small arms almost exclusively; it is ordinarily omitted from the English translation of the name.) As of 2015, its members are the national governments of 14 countries, of which 11 are European Union member states. The C.I.P. safeguards that all firearms and ammunition sold to civilian purchasers in member states are safe for the users.
To achieve this, all such firearms are first proof tested at C.I.P. accredited Proof Houses. The same applies for cartridges; at regular intervals, cartridges are tested against the C.I.P. pressure specifications at the ammunition manufacturing plants and at C.I.P. accredited Proof Houses.
