John,
Try this:
"I have had the same experiences as Harry C with insufficient rim recess. My fix for getting the gun to open was to place the receiver and barrels in a well padded vice ( bottom of receiver and top of barrels at the breach) and carefully and slowly tighten. I often would hear a click, the top lever would move free and when removed the gun would open. I now have a complete set of reamers."

This is from a 2019 post on the same problem. It is possible gun was put away because it would not open, so, cases may still be in chambers.
