Morning 475guy,
I don't have experience with the big bore rifles. I need some though. All I can go by is that whenever some of us get together to shoot, I'm about the only one who doesn't complain about recoil.
I'm not trying to sound tough, but it just doesn't seem to effect me like some. Much bigger friends don't understand it.

Having said that, I'm sure a 458 Lott would definitely "effect" me!
Although if I make the rifle into the Lott, I would handload some "softies" to start with.

The 416 Rigby is always in the back of my mind for the other choice.
