We don't have as much black powder shooting as we did several years ago. We have Dixie Gun Works in west Tennessee I live in middle Tennessee. There is no shops that have the older black powder stuff like horns rifles and pistols that I know of. Most all of it now is modern day guns for deer hunting. Don
PS Giz that is some great looking horns you have. You can tell a lot of work and craftsman ship went into making them.
