The only way to verify a barrel is in or out of spec is to check it with an in-spec bolt.
I have had LOTS of 308 barrels fail minimum headspace in my shop due to plated bolts.
When those same barrels are checked with a good bolt, they pass headspace just fine.
The fix for out of spec bolts due to plating is to deepen the boltface by removing two thicknesses of the plating.
