Verniers are very good for measuring components and similar things with fixed edges.
But .22 scoring is usually done with magnifiers and hole gauges.

I have mine somewhere… probably in a trunk full of old shooting stuff.
If anyone is shooting groups that are measuring 0.010 I would think one of these would be more useful than a vernier. Because you will “see” any spillover outside the blanking plate that is officially sized for a .22 bullet.
They come in all sizes, btw.
I use verniers daily and they are wonderful tools for measuring solids. Not as good as a
mic… but very good down to .5 tenths. But when you start trying to measure things like holes in ‘soft’ materials (or by holding the jaws over something) there is a lot more than a few thou of “by Gish or by gosh” error.
Perhaps someone should design a magnifier with concentric rings built in at .010 intervals? Not sure such a thing exists. Or an “set”not go/no go type gauges. I would think they would be more reliable than holding a vernier over a hole and then subtracting a diameter. At least when coming down to thousandths…
Just a thought. Have not had coffee. Excuse for controversial remarks. Interesting thread. I’ll have to try this next time I get 52 out.
