Here's a couple suggestions I offer to guys flying with firearms for the first time. It's really no big deal as long as you use common sense. I'd recommend a Starlight case. IMHO, these are the best cases you can use when travelling. (check ebay). Pick up a couple TSA approved locks for your case. TSA can open the locks and they'll relock the case when done inspecting. Next, if you shoot reloads and have a custom load for your rifle, pack them in a 'factory' box. Full. I've seen where airlines refused to take plastic boxes, they wanted only factory boxes and they had to be a full box. I've seen guys put different caliber shells in boxes, and that went through fine. When in doubt, call the airline you're flying, and get the name of the person you're speaking to. Good luck and don't worry.
