The 458 Lott was developed by Jack Lott in 1971. It is essentially a full-length version of the 458 Winchester Magnum, using the 375 H&H case necked up with a straight taper and 2.8-inch case length. The 458 Lott solves the problem of compressed powder charges required to reach full velocity in the shorter 458 Winchester Magnum case. However, the 458 Lott requires a full-length (375 H&H) action, while the 458 Winchester Magnum was designed to be housed in standard (30-06) actions. The 458 Lott became a popular wildcat and was added to the Hornady line in 2002. The 458 Lott is considerably faster and more powerful than is possible with the 458 Winchester Magnum, propelling a 500-grain bullet up to 2300 feet per second, thus more than adequate for any game that walks. Adding to its versatility, lighter-recoiling and readily available 458 Winchester Magnum ammunition can be fired in a 458 Lott chamber with absolute safety.
