[QUOTE="MNbogboy, post: 1844686, member: 18849"] Have you shot it since your cleaning? It looks like you got most of any carbon in the neck area as the reamer marks are mostly visable. Carbon in this area impinges on the neck not allowing complete bullet release and hence increased pressure. An old trick was to insert a bullet in a fired case. If it slips right in then the carbon ring in the neck was not the offender. A carbon ring in the throat itself often can be seen as it leaves marks (scratches) on a bullet when fully inserted into the throat. These bore cams truly are a godsend when examining before/during/and after cleaning. On another note, is the ammunition showing the ejector marks different in any way than when it didn't have pressure indicators? Any change in brass, powder, bullets or any other components could show an increase in pressure. Also was the ammunition "older" when these indicators showed? Possibility of "cold weld" could also boost up the pressure. Hope you nail it down. [/QUOTE]
