[QUOTE="MagnumManiac, post: 2851923, member: 10755"] I have made my own, but Larry Willis at Innovative makes one for most datum sizes. The problem with a comparator is the radius left on the edges of the hole and if you run a bore gauge into them, they’re not exactly what they say they are. Other than what I made for myself, the best measuring tool that is easily sourced is the RCBS Precision Mic, very accurate to .001”and I have never found a bad one. I have also found bad go gauges in the past, not common, but sent them back. Comparators are only good for comparing fired and sized case datum measurements, but measuring headspace, nope! Cheers.
