Years ago there was an "The Way I Do It" on gun building in 'The Buckskin Report' magazine.I cant remember the fellas name , but he used a boiled linseed oil over several days letting it soak in sun or next to the woodstove.He wet sanded the initial coats and rubbed in to fill the grain.After the stock wouldnt take any more oil, he kept rubbing it down until it quit bleeding out oil,then let it dry for a day or so depending on feel.He then took a pint jar,put boiled linseed oil about half full and a marble size chunk of pure beeswax in the jar.He then put the jar in a pan with an inch of water in the pan on the stove at low heat to melt the beeswax.Once the beeswax wax melted ,mixed the two together with a stick.
To apply,put it on hot and rub in with the heel of the hand, just a dab at a time until the grain is filled smooth.
This final finish could be put on for touch up at any time.
I've used it on several guns and it leaves a real low luster finish .
