[QUOTE="Goofycat, post: 672689, member: 6504"] .000020 accuracy is commendable, but for purposes of bullet runout and realignment it would be a bit much; I mean, who can tweak bullets to such a minute amount? Accuracy out to ten thousandths seems to be the top end on practicality when working with cases and loaded cartridges; for my varmint-shooting accuracy at ranges of 400 yards maximum, I would opt for tolerance measurements in the .001" or .0001" ranges, unless someone else tells me differently. I appreciate your reminder that we should always consider each point on an instrument that might offer the possibility of wear. If the instrument is to be used extensively for measuring thousands of rounds, for instance, I think that wear would be a serious consideration. For my purposes, I would be using a concentricity gauge only for quality-control purposes by taking sample concentricity/runout measurements only occasionally, thus making the wear factor not that important in the grand scheme of things. I.e., I see no reason to drive a Ferrari to go to the grocery store. With the wear factor not holding much weight for my purposes, my concern would be more with the inherent lack of good design, materials and construction. Bad bearing material, for instance, would doom a gauge at the outset, as would bad design in their placement and rotation in the gauge itself. I haven't seen anything offered by any of the gauge manufacturers as to the accuracy of their instruments out-of-the-box and as to how long such accuracy would last. I assume we just trust them by buying their products and keep our fingers crossed? Such a shame that we don't have an outfit such as Consumers Reports so as to compare these items.....or do we?
