Just my first posting to the forum. Taa Daa!
In the past many rifle stocks were finished with BLO.
Once the sanding was all done and any stain applied and sanded to remove whiskers raised by stain.
The wood was wiped down with a generous coat of oil and allowed to absorb as much as possible, dry spots hit again to get an even coating.
Allow twenty minutes or more so it penetrates the wood. then wipe down and let cure over night. Sand lightly to provide some "tooth" and remove any whiskers or anything else that shouldn't be on there.
Now comes the hard part.
Apply a light coat with a lint free rag or your bare hand, and rub with the grain all over creating enough friction to make your hand warm. (Don't worry it will wash off) There shouldn't be any wet oil when you are through rubbing, but to be sure polish with lint free cloth ( I like OLD T-shirt material ).
Next day do it again, and again until you achieve the finish desired. Some put on as high as 15 or more coats. A nice satin finish is the result and doesn't need anything else.
Years ago I built a BP rifle from a kit and used Beverly's Lin Speed and achieved a beautiful deep gloss finish after following the same procedure. If someone can tell me how to upload photos I'll try to add one of it.
It's a lot of work but other methods don't match the results, or the satisfaction. JMHO
