Is it possible that brand new brass might show the marks a bit more often than brass fired a couple times. On older brass It looks like nothing new has happened. Brass a bit soft?Maybe if your velocity is inside published velocities for your bullet weight then maybe its just soft brass and or a natural part of gas gun cycling, which is pretty hard on cases. If your not getting any other signs of pressure maybe just chalk it up to the abuse of gas gun operation and call it good.
