Has any one else had their Proof Prefit time up a little funky. I took an Impact Prefit and threaded on my OK built Surgron 591. This is a 6mm Creedmoor. The logo ended up about about 1/4 turn out of time. So I used a 6.5 Creedmoor go gauge and the bolt closed, with the no go gauge the bolt would not close. Can someone confirm this was measured correctly?
