Agreed. I used to transport broadcast TV gear this way. But just declaring your gun doesn't keep TSA out of your luggage unless you do it as you described. Use your gun case as your bag, then you can lock it with your lock and then you are much more secure.
I assume you mean using the wire loop for the internal gun case in your luggage?
Yes, thanks, fixed it.
I also declare this: the strategy of the oversize gun case w/ a locked wire loop to the internal bars of my luggage came straight out of swinokur's Airline/Firearm Travel playbook...thanks.
