Originally posted by stubert: You will also have quite a long jump before hitting the rifling, There may be an accuracy issue.
If it is a rechambered 458 Win the bullet jump should be the same. If the Lott is a SAAMI 458 Lott chamber then firing a 458 Win should have less bullet jump than when fired in a standard 458 chamber.
The SAAMI 458 Win has the rifling about 1" or 1.1" from the case mouth and the 458 Lott is about .4" or less.
