[QUOTE="Bill Johnson, post: 1065208, member: 84129"] So your ejector sits flush with the bolt face when fully depressed and doesn't protrude beyond the bolt body as noted on their home page? It's not unusual for some actions to allow high pressure loads to leave an ejector mark like that on a case, so as long as the ejector meets Stiller's criteria, that's OK. Just wondering what they had to say about it. Primer cratering, in and of itself without any other signs of high pressure, like hard bolt lift is not necessarily an issue either. What you do have to worry about is a primer failing to contain the pressure when it's deformed like that, though. Commonly called a "pierced primer", the hot gasses leaking into the action will erode the firing pin hole further, exacerbating the problem. I'd insist Stiller fix that but if they're adamant, you should consider switching primers to one with a harder cup. Federals are known to use the softest material. Switching to CCI or Tulas will reduce the cratering and give you a little better margin of safety. Good luck! [/QUOTE]
