Heading back to the range tomorrow, or later tonight, for that info, Madcat. I did some ladder loads from 27.0 - 28.5. This early summer heat may cause problems. 28.7 sure popped!!!! One thing I always do for my reloads in my AR's.....polish and slightly round the edges of the ejector plunger. Probably the reason for no swipes on the case head. I'll post when I get back.
