Borescope of Mos-Tek 350 Legend Barrel Crown

New custom barrel that I am evaluating. Initial bore-scoping didn't look too promising with the crown and bore looking a little suspect. Chambering and throating looked pretty good though. This is after firing 30 round or so. Accuracy isn't looking promising either. I am wondering if the termination of the copper following short of the crown is indicative of an issue.
