Which cci primer were you using? The 400s have a thinner cup than the 450s and BR4. I had 5.56 service rifle loads that pierced primers with the CCI 400s but were fine with the 450 or rem 7.5 primers with thicker cups. Also too large of a firing pin hole in the bolt face can lead to pierced primers.
Best, PA |
