Bolt doesn't lock back on last round, case necks are sooty, and the primers are still round, no flattening at all. That is what has me confused here. I measured and case capacity was only .4 grs less in the X39 brass. I am using Remington LRP, they are middle of the pack as far as burn goes. But I will back off 1gr and see what that does. If it gets worse I will just wait until I have proper brass for it and just use this in the Grendel when hunting.
