[QUOTE="bigedp51, post: 1421669, member: 28965"] I'm sorry but if the case is thinner on one side when fired the case body becomes egg shaped. Meaning the thin side of the case is bulging more after firing. Then when the case is full length resized the sizing forces cause the base of the case to tilt and no longer 90 degrees to the axis of the bore. And the amount of shoulder bump and head clearance will eliminate any tilting of the case if it was touching the bolt face. So go back and read what Mr. Salazar was saying in my post #10 and how full length resizing eliminates the case body from having a effect on bullet alignment. Meaning how a warped banana shaped neck sized case can effect bullet alignment. Or as the late Jim Hull and Kevin Thomas said "The case should fit the chamber like a rat turd in a violin case". So again when you spin the case on the body of the case in a runout gauge, is the runout caused by a egg shaped case or a off center case neck. [/QUOTE]
