Yes it is but sanding the stock is to finish it is wrong. Knock it down with 4 0000 steal wool first. wipe it down and blow of the steal wool with a air hose. Just put on a coat of Tung oil. Shake it up real good before use...(Don't shake varnish if you decide to use it. It has to be stirred.)
Apply one coat, let it dry and use four 0000 steel wool to knock it down. Keep doing this until it has the finish you like. I don't get too carried away if it;s for hunting.
