I am sure we have been here many times before. The method I use to remove the oil from a heavily oil soaked gun stock is heat over an extended time with a method of absorbing the oil as it leaves the wood.
I use an electrically heated gardeners plant propagator. With Clay type Kitty litter to absorb the oil that comes out of the wood so it does not have the chance to flow back in to the wood. Because the heating element is so low there is no chance of the propagator damaging the wood at all. The method is simple place the stock in the propagator and cover the most oiled parts completely with Kitty litter and turn on. Just for information the propagator in the p[hodographs has had gun stocks left heating for the largest part of a year with no ill efects.
