OK I see it now. I was looking at the photo wrong. I thought the two tubes on their sides were other dies. It made me think there were more stages to the process. When I make .219 Donaldson Wasp cases from 30-30 brass it requires annealing and several forming dies. They don't all make it to the end. Let us know how it works.
