[QUOTE="milanuk, post: 255501, member: 376"] Looking for input from people who do use a concentricity gauge such as a NECO, RCBS Casemaster, or other home-brew devices to check case wall runout. I'm attempting to do same with my NECO gauge, but I'm finding the directions a little... off, mainly because the test indicator pictured in the destructions is a different model/configuration than what I have (mine is newer), and basically, I can't really make it work that way without breaking/bending something. One person I've spoken with uses theirs to 'spin' the cases and get a running TIR number; despite having several conversations w/ them about it I can't seem to manage the same technique with any degree of accuracy (needle swinging all over the place). I've tried marking four cardinal points on the case body and taking static readings... results seem to vary wildly there as well: one batch (fireformed, but cleaned inside and out) showed very little variation, another batch (virgin, but same lot) shows 2-3x as much runout. Getting a little frustrated here... TIA, Monte [/QUOTE]
