Thanks for the link, oskar. I think the newer brass I have is Bertram and, in spite of annealing, I lost one case on first firing to a longitudinal crack. I just wrote Der Ami that I'm going to dig out some new Norma 9.3x72R brass and give it another try. I had been shooting it in original Berdan brass. Still have some old factory rounds left.
