I done the same to one of my stocks.
I stripped it completely , gave it a good rub down so the wood was nice and clean.
I then used Colron liquid wax from homebase, rubbed in with fine wirewool.
It turned out quite nice and showed the grain up nice.
Plus now I find it easy to repair if I scratch it while out hunting.
A few people have have said how nice it looks for a beech stock.
