[QUOTE="Dean2, post: 1865518, member: 26077"] I would compare this to a once fired factory load but at least my initial though based on your measurements is that resizing isn't the issue, the problem is your loads are WAY too hot. That much case head expansion at the Web is a REALLY bad thing. Page 85 is the Saami specs for the 270. If your measurements are accurate your brass is starting out way undersized but you also should not be getting .0-06-7 expansion on the head but the brass will expand to fit the chamber even with modest loads.
