Allen I built thst Great Plains rifle kit back in the 1980s. I browned the barrel and did some German silver stock inlays. Nice silver scorpion inlaid on top of the wrist. It looked great and shot better. I broke down and sold it to a friend. He loaned it to another friend who didnt want to spend pennies on a cap fired before loading. He decided to blow the bore clean with the compressor. Condensation locked up the patched ball which he left over the week-end resulting in a heavy rust ring in the bore.
