Sounds like you got a hot lot! What was the speed on it?
I am in Lapua brass right, not sure of the difference.
Didnt chrono it. Was looking for accuracy'
Loaded some 6.5 CM out of same jug with no problems. I was 1 grain off max on the 6.5
Pulled them down and verified charge weight, OAL and bullet weight
I read where Shaman had problems with pressure too with same powder
