I don't suppose somewhere in that wazoo you have a #3 bolt head for sale, do you?
Even Springfield Sporters only lists #0 and #1. The #3 heads have gotten pretty scarce.
My best advice is to check other heads with calipers, or by trying them in your rifle with HS gauges. They do vary, even when they're supposed to be the same size.
Oh, and which spec gauges are you using? SAAMI no-go is 0.067", but the military spec is 0.070". The military field gauge was 0.074". Lots of rifles that fail with SAAMI gauges would be considered perfectly safe under the standard to which they were designed and built.
