Does anyone make a suitable 10 round ammo case for .505 Gibbs?

Suitable for FAA requirements?

.

MTM makes a case that hold 18 rounds...MTM RF22-LM...that will close with Hornady or A-Square bullets but not with Barnes (my preferred bullet). I use an MTM Survivor Dry Box and place my ammo in Factory Hornady boxes, the dry box will hold 2 factory boxes and is lockable. Send me an email and I'll send you a photo.
