What strength, if any, would oiling of stocks add to a stock? For example, would a heavy recoil rifle, like a .375 Holland & Holland, be less likely to crack if oiled? Does the type of oil matter? Would a more transient oil such as OTC lemon oil/ furniture oil be satisfactory? Or is a more permanent oil necessary, such as tung oil, which really hurts the original appearance of a 19th Century firearm? Any chemists, engineers, or physicists willing to comment?
