I am in the process of changing my dillon 650 over to 9mm from 38spl, and I am encountering scratched cases from my 9mm Carbide sizing die (Dillon type). This cannot be normal. This problem has never occurred in the 1,000's of rounds I have reloaded in 38spl.
Does 9mm require lube because of its tapered walls? Or am I doing something else wrong?
Any help would be greatly appreciated.
