Thread: See separation?

Do you really need to anneal the cases, have reloaded for 40 plus years and never annealed any of my brass. I do get split necks after a while but usually get quite a few loads from them before this happens. Some brass is better than others and seems to go forever. Most of the time the first thing to go is the primer pocket enlarges and then I chuck the brass.
I suppose different rifles have different effects on brass too so there are a lot of variables out there.
