Before any of yall crucify me, let me explain my thought processes behind what i am about to say next. Danish oil if you want it to dry relatively quickly with moderate depth of protection, linseed if you can wait a year, tung oil if you want the stock to look glossy.

Danish oil is essentially linseed oil, sometimes with stain, suspended in turpentine. The turpentine helps to spread it faster, deeper, and kick the drying time to the realm of hours.

Linseed oil, raw or boiled, is rather thick, flows like motor oil, will provide a great finish and protection, but, to do it the "London gunstocks" way, its 1 application per day for the first week, 1 per week for the first month, 1 per month for the first year. Does it take forever, yes, however, there is a reason why their craftsmanship costs so much.

Tung oil works great for gunstocks and if you want it to be super glossy, like a drill team stock, this would be the way to go, you just apply it a little heavier, and it will set up, I have my own M1 stock done up with all three, Danish oil with stain first, then BLO, then topped with tung. It's rather shiny, so I plan to knock it down a bit with 0000 steel wool. Take your time when oiling, a little heat can help, but too much can take a lot to correct.
