That's weird Jeff. On my several trips, using an aluminum case like yours, I had a couple of keyed master locks on my rifle case instead of TSA locks. I was told that I should be the only person able to open that case, not some bunch of idiots who all had TSA keys while I wasn't present.
I was told similar by Delta. They told me to put Non-TSA lock on all lock holes. Your case should only be able to be opened in your presence and the employees should not even touch your rifle, as they are not trained to handle firearms. The ammo should be stored in a separate case with TSA locks.
