[QUOTE="velvetant, post: 1315138, member: 25670"] I'm only assuming here but I think you are measuring the case expansion ring. All that tells you is your chamber is tight or sloppy. If you are after case head expansion you need to be out 4 decimal and anything over .0005 is considered a hot load. You need to use a blade micrometer to get the area just above the extractor groove any further up and you start getting back into the expansion ring. [/QUOTE]
