I always wanted--but never did--to hunt elk or moose with a .458 and the 350 grain TSX. That bullet has three grooves and the .458 has a long freebore. You can crimp it in the second groove and get what amounts to a higher case capacity. If you have a CZ, you can crimp it a groove farther. A guy who used to post here under the handle 458only thought this up. You get the same case capacity as a Lott. I have loaded this bullet to 2700 fps easily. A 30-06 on steroids? According to the computer programs, you get 3000 foot pounds at 300 yards.
This is the way I am setting my .458 up for allround use. Am currently wringing out more loads and seating depths to find the sweet spot with that 350gn TSX bullet. There is nothing in the US that really needs the 450gn TSX offering but a few on the shelf covers any perceived need.
