I have a Win M70 .458WM
With 450gr. North Fork Flat point Solids and 72gr. of AA2230 it'll hammer anything and everything I may ever hunt with less felt recoil than my AHR Lott.
Damn right Fost, and I hear they make a Cup Point solid too that penetrates like an expanding solid.
Spose to be bad to the bone.

I'm taking a handful of 450gr. NF CPS next month to Zimbabwe. PH has never seen them, and is interested in how well they perform.
Back on topic for the OP:
With the availability of today's premium bullets and powder, there's honestly no
real need to convert the .458WM to a Lott.
Unless of course it's just and itch you have to scratch just 'cuz.
