"...a test fire..." That just test to see if the rifle will go bang. Nothing else.
"...It is not rocket science..." Needed to be bigger. snicker. You need a No-Go and a Field headspace gauge(that you can buy or rent with no fuss). No bits of tape, empty cases, gum, empty cases or anything else. Slip the No-Go gauge under the extractor and gently(no force at all) close the bolt. If the bolt does not close completely, the headspace is ok. However, if it does close, do the same thing with the Field gauge. Again, if the bolt does not close completely, you're fine. If it does close, the headspace is bad.
The CF(CDN Military) on the.303British page(Steve Redgwell.) didn't use Field gauges. That'd be the .74 gauge mentioned. If a rifle failed the check with a No-Go, it was taken out of service.

"...I am not an SMLE guy..." That'd be good. A No. 4 Lee-Enfield IS NOT an SMLE.
