No case feeder, and bench is level and solid.
Sorry, I left out that little detail. 9mm brass. It’s the only caliber I have a problem with. The shell will not align, and enter, the sizing die(s). The dies are at least 20 years old. Niether is beveled/ radiused.
As mentioned above, I probably just need to order a sizing/decamping die. I can’t see trying to grind a carbide die with a ball stone. Could that even work?
