Go to my forum link and check out Muzzleloaders, I redid coreys Hawken and did a complete type up on it.

With tru-oil, dip your finger in and put little dots over a 2 or 3 inch section of stock and rub it in, keep doing that until you have the entire rear of the stock done on one side. Let it sit over night and do the other side. Its a whole lot easier doing it one section at a time and comes out smoother. I did 7 coats i believe on coreys hawken and then finished it off with 2 coats of tru-oil in a spray can.
