[QUOTE="rscott5028, post: 635322, member: 24624"] Gary, I consider you the master of working with close tolerances. So, I wouldn't knowingly disagree with anything you stated on the subject. I would simply ask the question as to how you would consistently take such a precise measurement as requested by the OP (.0001") if you aren't certain that your case head is square to the body to at least the same degree of precision? Most digital calipers will give a reading to the nearest .0005". I have no idea how trustworthy that reading is. But as a relative comparison, spinning the case will cause the reading to fluctuate which I suspect is a function of (a) pressure/technique, and (b) case heads that are slightly out of square. i.e. ye olde banana case theory -- richard [/QUOTE]
