i have a 6.5 creedmoor barrel coming in this week from jim briggs but now i cant seem to locate any headspace guages pt&g told me it would be 2 months for them then they have to fill the back orders first,elk ridge reamer rental said atleast 3 weeks at the soonist,and 4-d rental pretty much told me it aint happeneing . anyone have another place to try? the other idea i came up with is since i have to swap heads on the bolt to remove the ejector,extractor and firing pin and use a factory round to set the head space then add a peice of tape for no go. what do ya'll think.
