It depends on how you reload them, but I find after 3 loadings, the necks get a little brittle. So I anneal them then. At the same time trim and FL size. I usually get 3 more loads out of them. If I FL every time, then I might shoot them 5 times. I have never had a case rupture or pulled the rim off, knock on wood, but know my time is coming one day.I have shot pistol brass however until it started splitting.
