[QUOTE="Calamity Jake, post: 2141441, member: 12219"] Primer appearence is not a good indicator of over pressure although a lot of reloaders use it, the raised areas around the FP strike could be from an oversize FP hole in the bolt face. The first case in the pic has a pierced primer from the long FP used for the Russian primers. Cases 3,4 and 5 are overpressure for sure as seen by the extractor/ejector marks on 3 and 5 and the blown primers in 4 and 5. [/QUOTE]
