I have a Revolution that has shell plate issues. On almost every complete shell rotation. The shell plate will not advance. The tool head goes down again and adds another powder drop to an already filled case. Yep, powder all over the place. I have had the shell plate out twice and can't seem to see any issues with the plate. I noticed the rotation pawl is spring loaded and seems to be fine. It looks like it retracts far enough to grab the index hole in the shell plate to turn the shell plate. I have the large nut tight so there is no side to side movement across the plate. Any ideas?
TIA
Mike
