My bore must be smaller than .729 because with a .715 ball and .010 patch, it becomes very difficult to load after two shots. I have switched to Lehigh Valley lube and like it - also wet with a dry wadded up patch between powder and wet patch. Can't find Lehigh anymore - is Shenendoah Valley lube the same stuff? The bottle and label looks the same. I think the guy copied everything from Lehigh.
