interesting that 2825 was calculated. that is what JBM velocity is to get 1.5" high at 200 and the 2.5" high at 100yards ***Sorry mis-posted it earlier stating it was 2.5" at both 100 and 200 yards***

But that pressure is extremely high isn't it? SAAMI is 62,000PSI correct?

But I did not see any pressure signs with the loads though...... No flatened primer, no hard bolt lift, pressure ring measured same as factory ammo brass
