This may sound like BS but there' s a physics formula for recoil and it' s based on Newtons law of action and reaction. However certain stock designs can convert that reaction to barrel lift and others can cause pure " reaction" . The difference between recoil and " felt" recoil can be fairly large.

I have a Remington 721 in .300 H&H that was a very pleasant gun to shoot until I restocked it.
