I recently installed a Satern 6.5 Grendel barrel and discovered that the bolt will not close on a PTG headspace go gauge. I understand that there are some issues with different specs, so I just want to confirm whether or not I will have a headspace issue with the new barrel.
I have not been able to get the chamber specs that Satern used, but I do have the print for the gauge from PTG. Measured from a datum line at .350 on the shoulder I show the following:
PTG print length: 1.2201
Actual gauge as measured with my .350 comparator: 1.213
New unfired lapua brass with .350 comparator: 1.206
The unfired brass chambers easily, so I know my actual chamber headspace is some where between 1.206 and 1.213...I just want to confirm that this is correct to Satern's specs and there won't be an issue firing this rifle.
Thanks for any help.
