[QUOTE="Clark, post: 1669984, member: 6600"] One might try to calculate the threshold of recoil pain. I have found the skin nerves to feel pain at ~20 psi. To get from rifle movement in foot pounds of rifle recoil, MV, or V to calculating psi on the skin takes some doing. One needs to know: 1) the area of the recoil pad 2) the bulk modulus of the recoil pad 3) how well the shape of the shoulder fits the shape of the recoil pad. 4) bulk modulus of the shoulder [easier on fat guys] I have been through this, but you don't need a calculator to know your win 94 30-30 narrow hard butt makes more pain than your 338WM with the large Limbsaver grind to fit, with no grinding done.
