BB, I agree that Weatherby will get this corrected. Here's an idea for you: plan a hunt in Wyoming (there is some great hunting there) and bring an extra airline/TSA approved rifle case. Before your hunt (or after) visit Weatherby, pick up your rifle in person (with a thorough inspection right there) and bring it home with you. Would Australia allow you to do that? Just a thought.
EDIT: Who knows, if Adam knew you came all the way from down under, I bet he would make time to step out to the showroom and welcome you personally and make sure your rifle is 100% satisfactory.
