Go-NoGo Issue is Resolved !
Well heard back from the gauge manufacturer and their gauges were on spec within .0002 ..... very precise.
What was not on spec was the Lapua brass, being .006 undersized and the Hornady being .002 undersized.
The hornady is fine but the lapua is a little to short. My head spacing using the Lapua brass and very lightly touching was the correct thing to do the manufacturer of the gauge and I agreed. I told him I like to keep both my eyes and all my fingers, and he feels the same ;- )
Just an update.
