If you are planning on hunting with it, I would sand it down, give it a good rubbing with 400 and 600 grit, apply a coat of boiled linseed,diluted with lacquer thinner let it dry for a couple days, then repeat. Then, when good and dry, rub the stock down with 0000 steel wool until you feel no bristles sticking up through the finish. Now, use undiluted linseed and apply up to 5 or 6 more coats, allowing each coat to thoroughly dry. When finished, your stock will look great, and be protected from the elements. then, if you happen to put a ding in it while out , it is an easy fix, more linseed.
