I have a huge problem derimming the 22 lr brass for jackets. When I derim the brasses, I have a whole lot of them at the base with what seems like a crack after derimming them. I assume that’s bad and cast them away. How do you remedy that problem? I remember seeing someone’s thread here somewhere about annealing before derimming it so that way it most of the brass won’t go to waste. Can someone tell me more about that?
