Try mixing a little "japan drier" with the boild linseed oil. It cuts it a little and helps it to dry faster, and stay dry. I have used boiled linseed oil on a lot of things, even water proofing tarps, haversacks, etc. That's the only finish I put on my fflintlocks when I built them, that and boiled walnuts for a stain. The more coats you apply the more shine you will have. The main thing is to put on many light coats, rub them in to the wood with your hand. You'll get a really nice finish out of it and as others stated, it's a "soft" finish, not hard like a varnish.
