Jerry 45,
Your last post makes a much clearer picture of why it is the brass that is the issue.
The annealing caught my eye, too. It is not clear to me if there were any blow-outs before the case had been annealed at least once. Can you be more specific about that?
Also, when annealing, as you finish heating the case (which you are holding in your fingers), do you drop the case into water, or just set it down on the bench to cool?
