Honestly forget about mixing this and that to get a good finish. There are numerous finishes on the market specifically made for wood gunstocks.

Chem Packs...... Pro Custom oil in in a can or custom oil in aerosol. EAsy to use and gives great results.

Permalyn..... Time consuming but produces an exceptionally hard and beautiful finish.

Tru Oil.... Easy to apply and if you follow the directions it produces a fine finish on wood.

I have used all three of these and they all produce very nice finishes. If you got the time (a couple of weeks) the permalyn is the best of the bunch.
