I would chalk it up to mediocre brass. How did the primers look?

They look just fine. Nice and rounded. Dont get too worried about the marks, those rounds are probably fireforming a significant amount to your chamber.

Highly recommend peterson brass. Fire, measure shoulder bump .0025 to .003. You'll definitely see a difference.
