I did shoot today and will post a full report when I get to a PC (on my iPhone now at the pool) but I don't know off hand what happened to your groups, but 200gr XTP over 9.2gr LS should probably be 8.2gr. I've shot up to 9.4gr but HORNADY max is 8.2.
Is that a typo?
Also, I will day that your case splits look like a brass defect not a over pressure but I could be wrong.
I'll get on an post this evening with a full report as promised but I will say, in short, Gator378 and I had a great day at the range!
