You can make everything to reload them unless you just want his. Well they use 209 primers don't know what to tell you to use to knock out the primers maybe a piece of 1/8 inch welding rod wit flux knocked off drill you a hole in a block to knock them in. I would use circlr fly wads RMC well no what wads you need. find something that will fit in the shell hole to compress the powder a little. good luck ch I don't think they would be like ballon head since they are turned on a lathe
I've hurd they work well
