So after a long debacle of fooling with this, I have arrived at Hornady One Shot lube. It seems to be very nice and a lot better than what I had been using. The rims on the .556/.300 BLK cases aren't very substantial and this stuff is really reducing sizing effort. I am think it was a lube issue that exposed a few other weaknesses and it seems to be resolved for now.
