Wrinkled necks when formed from 6Gren ??

I have never liked Hornady brass for reloading. But that is me. How many times has that brass been fired period? Did you anneal your brass before the forming process? It sounds like was too hard and when you fired it it just cracked. I always anneal my brass before reforming a case even brand new brass that has been annealed from the factory.
