Personally I can tolerate up to a 458Wm/470 NE, no problem.
My 416 Rem has teeth because of its weight and the "sharpness" of the punch.The stock design helps much though. My 500 NE is going to be an eye opener, i am sure.

I don't feel the formula on AR is entirely accurate as I feel the VELOCITY of the energy of recoil is the more important variable. Slow that down markedly and we all would be shooting bigger boomers.This can be done by more weight(obviously) or some type of recoil assistance.

The other variable is hunting adrenalin. Some shots I can't remember feeling cause the animal in my scope.

Oh, well--
