6br Head to Datum Measure

[DaninFL]

The SP/Horn headspace gauge measurements give the following for Lapua brass:

New, unfired: 1.155"
Sized, shot five, six times: 1.157"
Loaded: 1.158"
Fired, shot five, six times: 1.159", 1.160"

The rifle is a Savage, F-class (they do shoot!), 105g Hornady, 29.9g Varget, Wolf mag small primers. I use a Wilson guage for all calibers except the 6br. (Wilson would not work!) Are these measurement "nomal" or is there too much stretch? TIA Dan

Looks pretty normal to me. If you ahve not, you need to body size the cases to get the necks back to 1.556"
