[QUOTE="Mikecr, post: 705849, member: 1521"] RangerBrad, you have two signs of oversizing: -wedging/stuck cases -failure to headspace Other signs will be donuts & frequent need for trimming. How much is the brass changing in dimension from first firing? You might finish the fireforming & send 3 unsized cases to JLC Precision for a custom die. I had the same signs with Tubb's 'Ferrari of die sets' in 6XC, fired from a Tubb2000. I was using sizing wax which left cases stuck. Fixed with RCBS Case Lube. Headspacing was all over the map. Fixed with a JLC bushing bump die. Jim said my fireformed brass indicated a chamber completely incompatibile with Tubb's dies(gross oversizing). To be fair, McMillan Bros cut the chamber, not Tubb.
