Yes, call Weatherby, let them fix it or recommend. We need to keep these service departments in business and they need to know if something is off. A good service department will look up the manufacture date and discuss with a supervisor. That's how QA works. Please report back here if you do.
In a perfectly square action the top lug will not touch when checking it with the trigger in place. If it shoots goods just go shoot it. I bet you find with unsized fired brass it will start showing wear on that sharpie mark in short order. Those Vanguards are usually pretty good as they come.
