[QUOTE="Orange Dust, post: 1710452, member: 92702"] Hard to tell from the pict but it looks like there is an extractor mark on the case on the right. Sure sign of overpressure. Primers aren't really a good indicator of pressure unless you know the rifle well. Have you miked the case before and after firing? You have to use a micrometer not calipers. Some measure the rim, some measure the belt, and some just in front of the belt. To each his own, but ANY measureable dif on the rim is too much. So is .001 on the belt. Extractor marks are a reliable measure of over pressure for the lot of brass you are using. Bushing the firing pin will not change these. [/QUOTE]
