I just finished putting together a York County .45 cal rifle from a Chambers Kit. I am anxious to test fire it although I do not have any finish on the wood. I am wondering if firing and cleaning it will cause any problems (from powder marks, barrel cleaning, etc.) later when I go to put on a stain and finish on the wood? It will be quite awhile before I can stain it since i want to do some decorative carving and install a brass patch box.
