Thanks for the excellent advice. Things I never thought of that's why I asked. I really do appreciate the help. I been reading everything I can about cannons from old history to these forums and really enjoy what I'm reading. I live near Sacremento Ky and they have a reenactment there sometime in early spring. I dont know if they shoot cannons but I am gonna go there this year and check it out. Thanks so much for the response again.
