[QUOTE="entoptics, post: 1956800, member: 104268"] Have you tried the 200 ELDX factory load you mentioned in your rifle? If so, were there similar issues, or did it behave fine? Does the fresh Hornady brass measure the same as the unfired factory brass from base to shoulder? Also, how does the base to shoulder from the Seekins fired brass compare to the base to shoulder from brass fired in your 300WM? That will at least give you two points of data to compare. It's plausible that the chamber really is fine, but the bolt face is back too far. Case is stopping where it should when chambered, but when fired, it's moving back further than it should? A conventional no-go gauge would diagnose this problem I think. [/QUOTE]
