You don't even need to do that if you can find a small inlay that matches your personality and just cover the damage with it.. How about a state coin? Or some symbol that means something to you or your family? It can even be a blued piece of steel that looks like a repair.

If the finish on the stock is real good I thing a repair that is bragged about is better than trying to repair the stock and have this well finished deep hole in it.
