I am looking for a gunsmithing book or any resource that teaches you how to fit a shotgun stock.. I just had my Browning o/u fitted with a Kickeez pad. I think the stocksmith made the stock about an inch longer. This made a great big difference! It don't hit my cheek and I shoot much better with the gun now. I want to learn how to fit gunstocks. I have 4 field grade shotguns that have the plastic recoil pad on it. I would like to fit Kickeez's on all of them. Problem is, these guns are not worth the cost he charged me. I would sure like to take a shot at doing it myself. Any info is appreciated....
