I drop loading rod in barrel letting brass either" tink"against breech or "tunk"against lead. Treat as loaded always best. Do not drop ,snap,fire ,even without a percussion cap in place. you only need a spark. Yes i,m overly cautious. Charges have been pulled from old weapons. Dad saw one from musket after it had been to show and tell,passed around classmates snapping hammer. Lacking a loading rod,a dowel could be seated through bore,marked at barrel end then withdrawn and laid along barrel flush with muzzle(keep fingers clear). Nipple usually just ahead of breech plug. dowel end should be even with nipple at least or past toward grip. Any doubt visit capable gunsmith!.
