never....i shoot a flintlock and regaurdless of what anyone says its not safe to do in a flinter....a guy i know shot his a bunch of times...no power in the pan and it went of...took a lot of times but it did go off eventually....what if it falls over?evne in a shed or garage...someone or something will get hurt....i shoot mine at the end of the day...now if im going spot to spot i will leave it in the trunk and leave the frizen open..but at the end of the day its getting fired.....and i dont want to take a chance of the powder going bad in there and finding out when my deer come by.......
