I was shooting a .458 Alaskan for a while - 97gr. capacity, bit higher than the .458 Winney. In the post 64 Model 70 Winchester easily ran 2,200fps with 500gr. Hornadys but the recoil was too much for my much damaged shoulder cartilage, so I set the barrel back and re-chambered it for the .458 2", with which I damaged my shoulder in the first place. LOL
My buddy Keith needed it more than I did, so he bought it from me.

Unless you are driving the Lott at top speeds with an EXPANDING mono-metal bullet you would likely see ZERO difference in those ctgs. listed, on game- perhaps, just perhaps, an advantage or equality with the .470 - maybe.

This is just a wild-assed guess while I am drinking sprite with Isl. of Islay Gin & snacking on herring roll-mops. Yummy!
