grayfox... Your thoughts concerning the precision of the Hornady measuring tools are pretty much the same as mine now. I did the same checks with my Grendel brass & headspace gauges & got similar results. From those measurements it also looks like the bolt might close on a NO-GO gauge. It won't close so I am feeling pretty sure my concerns about my 6mm ARC will amount to diddly-squat.
The Manson shipping invoice just says 6mm ARC. It doesn't specify bolt-face depth. You're right, they should be for .136" bolts. I've never seen anything that would lead me to believe the 6mm ARC was developed from anything other than the type II 6.5 Grendel chambering.
