New AR308 build. This rifle will always host my Omega suppressor. I put 60 rounds of Federal match ammo through it. My newly fire formed cases reveal slight over pressure. The spent primers are flowing around the firing pin such that the spent primer 'crater' exceeds the case head by about .001"
My cases won't flush up against my micrometer for an accurate reading when using my head space comparator.
I intend to measure these cases so I can bump the shoulder .002" with my die, based on my rifle's chamber dimensions. I don't want to resize these cases in the process of removing these cratered primers. How can I decap these cases without full length resizing them in the process?
