[QUOTE="MNbogboy, post: 1805184, member: 18849"] Ah, but you did in post #49... Think that your chamber polishing may allow brass to extract easier especially through the flat section. The headspace reduction may help also by holding the case head closer to the bolt face. Hopefully reducing case stretch. The ejector marks and the even the case separation possibly are a result of "delayed" slamming of the case backwards do to the original "finish" of the straight section. The polishing in that area may help. Good luck on today's shoot, Randy [/QUOTE]
