This is a picture of the primers. The one on the left was loaded with 30.5 grains of varget behind 139 grain FMJ bullet. The one on the right had 28 grains of Varget. This also happened once with some factory Norma ammo , which came with the rifle (at least 10 years old). I shot 2 more rounds loaded with 28 grains and none exhibited any signs of high pressure. I'm using brand new PPU brass ( resized and measured with micrometer), Winchester Large rifle primers and PPU 139 grain FMJ bullets. BTW i'm John's nephew.
