I'm with WIL TERRY, lots of missing information here:
Are you trying to measure head space on the still un-repaired rifle? Is the one Ruger sent back the same one or did they repair/replace it? It is starting to seem kind of odd. It is also very unlikely they didn't send any paperwork with the returned rifle, very very strange.
If the rifle isn't repaired, why bother measuring anything?
