No signs of pressure. I’m going to contact the company tomorrow about this “precision” barrel.1. Over pressure, look at the flattened primer and where it cupped around the firing pin.
2. The chamber needs to be polished, it's rougher than a cob. Look at the circular scratch marks when you lifted the bolt.
I don’t normally use primers as gauges for over pressure, unless they start falling out. But that one in the pic does look ugly. Strangle outer ring around the strike and a funny looking gouge or something next to the strike mark.
Maybe just something with the camera, but you might take a close look at your bolt face also.
The ring on the primer matches the bolt face. The primers do not look or feel cratered.
I sent a couple pics to a gunsmith. He recommended returning it. Said he would have to cut the barrel and redo the chamber.
We’ll see what McGowen has to say about it.
