    I am using rem. brass, federal lmr primer, berger210 vld and 92g retumbo. My primers have a ring around them and have had 2 back primers out far enough to lock bolt closed. Dropped firing pin on them once or twice and bolt opened right up. The web of the case was within a thous. fired and unfired. Is this pressure or oversized flashholes in some of the rem. brass?

    What are the exact measurements?

    A few thou makes a big difference when monitoring case stretch as it relates to mag load!
