i would find another gunsmith...have no idea what 15thou is..
buy a set of gauges and check it yourself.
not that hard to do...buy the tools and ill walk you through it.

...have no idea what 15thou is..

= 0.015 inches, or 0.001 inch more than "the 14 thou. 30-06 field gauge (he measured it at 15 thou.). In a rifle with a huge camming action.

If the gunsmith, for instance, didn't remove the firing spring before using the gauge, he will hardly have been able to feel the contact between bolt face and gauge.

Buy a set of gauges for a one-off measurement? I wouldn't. Always use necksized reloads for old rifles.

It really is nothing to get into a twitter about.
