something to consider.......you can make a rifle to feed the 458 win mag round but chamber for the Lott! In this way you hunt with a .458 Lott round in the chamber but win mags in the magazine. Your first round is the main one I suspect anyway.......I doubt that many would choose this option but it's a doable option and if time permits one can manually feed Lott rounds individually

In fact today there's very little difference in the Win Mag and Lott rounds!

I'd really challenge one to ask if the difference is worth it!!!! If one needs more than the 458 Win Mag maybe he should be looking at something on the 416 Rigby case.

The standard '98 Mauser can be used for the Lott but as Grains says......spend themoney on an action designed for it in the first place.
