I haven't heard of using unboiled linseed oil. I've always used boiled.
I usually whip up a batch of gunny paste to rub into my old gun stocks. I have some old rifles that I wanted a military look to the stock. I stripped th em, 0000-steelwooled them, stained them the color I wanted, then sealed with the paste below.
Here's the recipe off another site:
"magic finish formula" consists of equal parts of Boiled Linseed Oil, Turpentine (essentially a solvent) and Beeswax. (1/3rd Linseed, 1/3rd Turpentine, and 1/3rd Beeswax. Melt the mixture over a "flameless" heat source (hot plate, radiator or the manifold of your vehicle). Stir the concoction and allow to cool into a paste. Put the paste in a convenient container (I used to use a typewriter ribbon can when they still had such things). You might get a can of Brie Cheese in the Grocery Store, those round cans work well and will fit in your shooting stool most handily inside of a zip-lock bag.
Take your prepared stock and start to rub the Beeswax mixture into the outside of the stock with the palm of your hand. Allow the friction (and generated heat) of your hand to melt the paste into the grain of the wood. You can do this while watching the "tube" and not screw anything up. After you have rubbed in the first coat, rub it down with an old towel. Repeat the process until you are satisfied (you can always add more, and this is one of the beauties of the finish, as it can be used until you get tired of rubbing). The last coat is always burnished with an old (Terrycloth) towel. The final "piece-d-resistance" is a quick final rubdown with a silicone cloth. The finish gives the appearance of a hand rubbed stock with 20 years of effort applied. The Beeswax imparts a waterproof finish to the stock, and any minor scrapes, or scratches can easily be rubbed out of it with a small addition of the Magic Paste. The finish looks good, has a non shiny military appearance, it’s waterproof, doesn’t smoke or bubble the finish in rapid fire and appears to be an original well rubbed rifle stock from the days prior to WWII. It truly IS a hand rubbed finish
