    I tried that but the cases would stick on the punch often enough to be a serious pain. How do you get around that? My de-rim die is Corbin.

    "in the morning I am going to fire up the oven and anneal"

    What do you mean by that?
    Liberals don't know they're stupid in the same way a fish does not know it is wet. It is just their natural state of being.

    Find a washer that just fits over the bottom punch. If one gets stuck, use it to lift the case up off the punch. Keep the punch oiled with swage lube. See my video, it deals with cases that get stuck on the punch.

    It would be less disrespectful to burn the flag than to put a thin blue line through the middle of it.

    I would be interested to know your finished diameter of your derimmed brass and the punch size for derimming. I find if I anneal first my derim punch must be far smaller than if unannealed. Also, is the rim all ironed out or do you still have a ring around the bottom? I am happy with my set up and have tried many different methods, punch sizes, annealing temps etc and have always come back to derim first with a .199" punch for most brands and a .197 for a couple of others. I am using a D Corbin setup.
