Oh, Nessmuk, that's a tough nut to crack. Since this is a personal challenge, it's up to each person to do it as he or she sees fit. As for me, "cold bore" means no patched ball has been shot from it, but I'm not laying down "the law." I have only tried once. I walked down posted the target, walked back, loaded old Clementine and gave it a go, then I muttered something under my breath. For me that meant no more trys that day from that rifle as the bore was now fouled. Great question, let's see what other guys think.
