Sand that stock smooth. then go over it with a damp rag. When its wet, you wil feel the grain "lift". Sand it while it's still a little wet. Let it dry, go over the stock with linseed oil, for two or three coats. Let it sit on the wood for about five or ten minutes, then wipe it off. Go over between coats with very fine steel wool. You will have a rifle you can be very proud of. I did a model 70 like this about two years ago. I think it turned out quite sharp.
