Boolit casters,
I have a used-once Lee six cavity .451" round ball mold. The balls cast by this mold would be good for a .44" revolver or patched for a .50" rifle. You can see from pictures, if requested, that it's in great shape and comes in the original box. $80 shipped to you or $60 shipped for just the mold, without the handles.
If you are interested, please PM me.
