This case is not advisable for checking separate. The latches can easily be flipped unintentionally as it gets shoved around in the belly of the plane and the only lock is the proprietary one. If the key is lost there is a big problem. Sure it can work but there are better and safer options.
The ammo case shown has travelled more than once as separate luggage on various airlines and I use a gun case with the same lock for 40 years. I have also never had any problems with it.
