Let me guess, the rifle is an AW? Mine have that same wide radius to the face of the pin and a sharp edge which will occasionally cause what you see in the lower left.
Primers are a crappy judge of pressure when headspace is on the minimum side.
When I look to primers for an indication of high pressure I look to see if the primer has expanded to fill the edge of the primer pocket. Yours look fine. The few with craters are probably more from the bolt face. I also don't see any ejector marks on the case head. How does your load compare to the book maximums?
