I'm much, much more alarmed at your addendum regarding the Hornady brass
It was a bit of a shock to see the Hornady brass Frankenmauser mentioned. They came in the nice little cardboard box, and were nice and shiney with no dents and nice even case mouths.........and then you turn it over to see the primer pocket. "off center" is a bit of an understatement for some of those cases. One i picked up was so bad that the flash hole was actually touching the side of the primer pocket, and several others were far enough off center, they would have no trouble bending/breaking a decapping pin if you didnt catch it during your case prep. Apparently the extra money for the Hornady brass (versus RP or Win) didn't really do much with this time around. Maybe better luck next time?
