No, but some wildcats do, that was my point. I don't think making AI cases is an accurate comparison because the changes to the shoulder are the equivalent to only a few reloading cycles.You fireform to double your bullet diameter?
You either don't understand how cases are formed, and how many handloaders make wildcat cases, or you're being a smarta$$. Either way your posts don't belong in this thread. You posted that you don't have problems with AI cases cracking at the necks, that was the end of your informative posts. Now, either tell the whole story or don't, I don't care, but I'm tired of arguing with you. There are definitely merits in annealing, especially when forming cases, otherwise the commercial manufacturers wouldn't anneal their brass during and after case forming. Do you not understand that?It wouldn't explain why I have primer pocket 'issues' because I don't use Federal brass.
Describe the process of fireforming a case to double the bullet diameter. Say Chambering A to Chambering B, your picks, in what chamber. Curious...
