My second "real" rifle was a 458 M70 pusher. I was boy at the time in Alaska and shot a ton of animals with it. I loved that rifle and shot my longest shot on a black bear that was 3/4 upright on a a fallen tree. I also crumpled a black bear that immediately charged me after messing up a shot and raking him through the guts. I really favor 500 grain bullets, which can be used on anything out to 200 or so yards. You would really only be limited by trajectory. Most 500 grain bullets have a very obtuse RN and make decent wounds at low velo. When you could get them to reload, I liked the old win 510 soft points.
I find the debate with the 458 win and 458 Lott funny. Both are great cartridges but also nearly identical not only ballisticlly but certainly categorically. People were ecstatic when the Lott came out but lately it has been suggested that it was never needed. As shooters we should never rationalize the existence of a cartridge, only our unreasonable purchases
