Guys, think about this a little please. Both the hole that the primer punch screws into and the hole that the index ball goes into are BOTH in the platform and no matter what position the platform is in the spacing between them never changes. That leaves either a shellplate that is too tight or the index block being out of position and that is it for centering the primer punch. The alignment tool is for setting the alignment for the shellplate to match the toolhead.
