[QUOTE="Winchester 69, post: 255661, member: 8037"] Monte, I believe what you're experiencing is the sensitivity of the gauge itself. The run-out gauge is far more sensitive than a dial indicator, and that should be its virtue. Another thing here is that you're measuring more than case straightness and wall thickness; you're also seeing every ding and imperfection in roundness of the brass. The thickness measurement is showing additional parameters to what a ball-end micrometer will. Your fired and cleaned cases have reduced these other parameters so that wall thickness and straightness dominate the measurement. I have every confidence that if you play with this thing a little bit and think about what you're measuring, you'll discover how well your NECO tool can serve you. I don't know how the new gauge is different from the one I have seen, but I expect that the change will mostly affect set-up. . [/QUOTE]
