I have a problem with an auction weapon that I happen to win the bid. It is a Charles Daly 50 cal percussion thats barrel is definently in bad shape I have been able to remove alot of the rust but it is starting to look hopeless. Well atleast I am getting some good exersize. I havent been able to remove the breech plug or the nipple box( the screw is frozen on the box) I have soaked it in every bore cleaner that I have and have read about all kinds of methods to get the rust out from coke to lemon juice but if any one else has any ideas I sure would like to hear them. If it is only a new barrel I would even try that if I can find one that will fit. Thanks for any help you can give.
