[QUOTE="Sam Summey, post: 1835423, member: 109601"] 2.5 grains over max is a mite stout. Is the chamber bright and smooth? Even with the chamber wall fairly straight the AI case may not be clinging to the chamber and loading the bolt face. It maybe being propelled against the bolt face giving the ejector mark. Might try roughing up the chamber a little so the case is stuck to the camber wall a little more. BTW my max load with 140 Sierra is 60.0 grains of IMR 4831. With the 162 gr Hornady 56 gr IMR 4831.
