Thread: Case base separation

Im not certain @Bagheera was looking for advice, more making a statement that if you work the brass enough this is what eventually happens? I expect this brass has had many firings.

With my .223 brass I eventually get little splits in the necks and it's time to biff them. I don't anneal .223. And I don't wring my hands when they split cos they have served me well with multiple uses.
