[QUOTE="CRNA, post: 519154, member: 22495"] Ok, so loading my 7RM. I tried measuring the primer pockets. I use this side of my calipers. working[IMG]http://i59.photobucket.com/albums/g309/screamin_chief/DSC_0011-1.jpg[/IMG] And I put this end in the primer pocket like this. [IMG]http://i59.photobucket.com/albums/g309/screamin_chief/DSC_0013-1.jpg[/IMG] And I get this number. [IMG]http://i59.photobucket.com/albums/g309/screamin_chief/DSC_0015.jpg[/IMG] Then I measure a Fed215 (you can see it in the caliper), and it measures this. [IMG]http://i59.photobucket.com/albums/g309/screamin_chief/DSC_0016.jpg[/IMG] Now, from all I have read, primers are supposed to be recessed into the pocket give or take about .004". If my measuring is right, then mine will ALWAYS be sticking out from the head of the case approximately this much. The whole reason that I tried doing this in the first place, was I noticed my primers seemed to be protruded. I measured 20 primed cases and wrote all the numbers down. Then I punched out the primers and remeasured. Sure enough, I found my case length shrank by........guess what.......about .004". What is going on? My primers appear to be too big for my brass. Is it me? Am I doing something really stupid here, or are my eyes and measurements agreeing that with this situation my primers will never go below flush the way they're supposed to ? Any insight would surely be helpful. OH!!!! By the way, measured my large rifle primers and they were shorter. They would actually fit in my primer pockets, but after working up a load with them, found me ES went all over the place. (Really bad, like an ES of 70!!!)
