Re: Gun shells
One of the side effects of 9/11 is that a lot of guns now travel in checked baggage by photographers and film makers. If you declare a firearm then your luggage gets put on the plane under armed guard and stored in a secure room at the destination. Much safer than trusting $100K of gear to the baggage thiefs.
Lovely example of making the system work for you by using the law of unintended consequences.
