Strange to say or perhaps to hear, I'd say that's just about the way every fitter does it. May not involve the empirical approach of adding quarters until you get a certain degree of down pitch which doesn't bust your chops; may involve just whacking the stock off at 5 to 7 degrees less than a right angle with rib because "most people are accomodated by 5 to 7 degrees down pitch". Raise the back sight (on a shotgun the eye)=raise the point of impact. Nothing new there to a rifleman or pistoleer other than the back sight is resting on bunion relief on the comb rather than on the frame or barrel. Quarters and moleskin are field expedients to "try" the results of whacking and bending stocks before doing so just as a trygun is a somewhat fancier "simulator" but still a simulator. G I Joe doesn't say whether he shoots every day with a stack of quarters as a shim or a couple layers of moleskin as a sight elevator. Bet he doesn't.
