Will be interesting to see the pics. Reading around the web lots of people complain about 6/6.5 Creed eating primer pockets after a couple of loads. I assume your rounds have large primers and are less tolerant of high pressures. Hornady shows those rounds running 2960fps which is at the higher end of load data. Are you able to chrono the rounds? Maybe your headspace is on the looser side combined with these loads.....but dunno.
