Maintaining the oil finish on a Sako
I just bought a Sako Bavarian that has an oil finished stock. It is very nice and is exactly what I wanted, a muted piece of lovely walnut. My question for is about what type of oil should I use to periodically maintain my stock and possibly make the grain pop a little bit more.
In my reading there seems to be a mix of opinions between tung oil and boiled linseed.
I would be very interested in the thoughts and experiences of people who have had oil finished guns currently or in the past. I just don't want to screw up the stock on a rifle that I spent a long time saving for.
