William_Iorg,
Was this with the regular or the AI version? I assume AI? Interesting you chose the 220 grain RN bullets. If like other RN they are probably undersized ahead of the channelure. This might help to reduce pressure, but not to the level you are documenting. Whether the 219 is a thing of beauty or not, it must be hell-for-strong, as must the brass.
I am fresh out of 170 gain RN but have a supply of HOR 180 SP bullets which I will try as soon as I get the 325 rifle up and running as an AI.
I hit a snag today when I notecd the barrel locking nut is cracked through. Had to sear for another. Once this is sorted, will rechamber for the AI version and begin recording the results.
Thanks for the info.
