I am new to the forum and new to black powder cannons and would like to know if any one knows about them. Are they of shootable quality and if so at what powder charges? Also I can't even find anyone selling balls for a 3 inch or 3.5 inch bore. Thanks for any help you can give me, I know I have a long road of research ahead of me on a lot of things, but want to know if these are quality before I start.
