I would also suggest the stock should fit the shooter, as to length of pull, pitch, and perhaps castoff..(caston ?).. Nest to that the size of the butt plate, width and height... bigger is better.. Don't use too soft a pad as the very soft padscan pinch when used on very heavy kickers.. The drop at the comb and heel of the stock and the thickness of the comb... all affect the felt recoil which is what we're all really concerned with.. The grip circumference and reach also can afffect the pain inflicted with a heavy hitter.. a well shaped forearm and grip(I prefer the Wundheimer swell) and good checkering, not too fine, will allow some of the recoil to be absorbed by the arms.. Also a very overlooked aspect is the proper weight. A featherweight mountain rifle in 300 Weatherby is going to crreate a recoil problem regardless of how well it fits.. The last thing I might add is barrel length.. For the hard kicking rifles a longer barrel put the blast a bit further away and the noise of firing adds to the 'perceived recoil' sensation. I also would suggest that a 'classic' style of stock is a bit more painful than a monte carlo stock might be but this may simply be the factories simplistic approach to stock design.. still a clasic style stock is more sensitive to design faults in the recoil aspect than most montecarlo designs.
