Now I would have said my 458lott recoiled about 25% more than my 458winmag. Some of that I think was because the lott was a ruger#1 and had a crappy recoil pad.
When i first got my win mag she had a montey carlo stock and a crappy pad. after restocking and installing a decent pad the recoil dropped off.
With a winterhat folded up and put in my shoulder I could take 15 shots with the lott off a bench with no ill effects. The worst time i had was in Zim last year i shot about 10 from my lott ,6 or so from a 450 ackley about 10 from a 12gauge shotgun and a few from a 375hh. My head didnt hurt but it was hard to raise my arm up very far.
