I went back out this morning to test a couple primers.
First was the GM155M that worked so well with the GG load in this rifle.---Still a lot of vertical (Top picture, lower group.)
Second was the GM150M. had a real good group of 3 going til i accidently touched one off just as I was getting into the sight. So I quit.
Then Decided to see what different alloys would do.
Using the GM155M primers, I cast a few in 12.5-1 and 20-1
The 12.5 got me under a 2moa vertical with strong gusty tailwinds, but the 20-1 wasn't even worth finishing.
Think I will go back with the 12.5-1 and the GM150M and see what I get.
OK, carry on with your anti PP discussion

Oh one thing I forgot to mention about flyers. as I was loading the second group, I realized I hadn't checked the case lip for peening on these and sure enough some had a sharp lip. maybe what was causing the flyers. Shells hadn't been used for almost 10 years.
