Really .1 Angstroms? Yeah that may be a bit extreme but I wouldn't say a tool with an accuracy of .001 or even .0005 is out of line for reloading. Just my opinion though. Might be getting crazy if you were using a .00005 accuracy unit- but I've known a few BR shooters to be crazy.
Ok then, my point was to the OP his gib screws were loose causing the gib to fall out of the tool. Which would affect accuracy way more than "just a bit". Probably just a quick tune up and would have worked ok- disappointing none the less for any tool out of the box be it $9 or $150.
If people are measuring things 10 times and getting 5 or more different readings, then it could be a couple things- an out of calibration tool or incorrect measuring technique.
I'm thinking a "Setting Standard" is being referred to as a Gage Block, possibly a (or for all those East coast macheenists I dealt with for years a "Jo Block"). Which in itself requires NIST traceability in order to be used for certified calibrations.
As for China made Mitutoyo products- they are multinational company. They have factories all over and items are made in Brazil, Mexico, Germany etc. The way of a global economy.
Merry Christmas everyone.
