I ran a few Hornady 6.5 grendel cases through the 6ARC dies and trimmed.Wrinkles or creases formed where the new neck was formed.I figured they'd smooth out when fired first time. On firing the creases improved some but most cases cracked or showed they were close to failing along the creases.Hoping someone can tell us where we made a mistake. Just received a new annealer and will now anneal all cases before re-sizing but... don't want to wreck anymore valuable brass.Been reloading literally 50 years now but have limited experience with reforming cases. Have a shoot tomorrow and don't want to use the few factory rounds I have. Thanks very much,Supervel
