I am trying to find a source to buy .590 lead round balls. I have a .60 cal flintlock that shoots a .595 ball with pillow .015 pillow ticking extremely well. However, it is very difficult to get the ball started. I have to pound my short starter with a hammer to get it started. Once started, it will go down with the ramrod but it is very inconvenient especially if I were to be hunting. I have ordered some .005 patches but I am just trying to find some .590's to use. .595 balls are readily available but I cannot find .590's. Any recommendations would be greatly appreciated.
