[QUOTE="xsn10s, post: 2309972, member: 95344"] Dented shoulders on the bigger 7mm cartridges could be a sign of a double pressure spike. I think it was with slower powder, sorry I cannot remember the details. I saw it once on the 7 RUM with certain powders. The thought at the time was the first pressure spike was enough to lodge the bullets into the lands but not seal the case in the chamber thus the dent on the shoulder. Then the second spike would generally be high. [/QUOTE]
