I was lead to believe reforming 32-20 brass to 25-20 is as simple as just running the 32-20 brass through the 25-20 sizing die. Well I can’t even get them to start without collapsing the mouths or necks of the Starline cases. Tried every type of lube I have but no luck. My 25-20 dies are from Lee. Is there a transition die I should be using?
