I've built 2 6.5 Creedmoor's for clients over the last few months. Today we put about 10 rounds through one I just finished and I noticed the primers were flat as a pancake with new Winchester 140gr ammo. I ran a couple through the chrono and they were 2750ish, nothing hot there. Then I checked them in the chamber, .006"-.007" headspace. I checked 1 Hornady I had on hand and it was .006". The chamber on a PTG go gage is .0015". Has any one else noticed this? Either my Go gage is long or the ammo is short....
