Ammo transport
It is up to the airline, NOT TSA, as to how the ammo is transported. Again I use Allegiant Air as my example because thats how I get to AZ. This is a quote from there website on firearms and ammo. I would strongly suggest checking the airlines web site you plan to travel with for there specific requirements.
Ammunition must be in the manufactures original container, or equivalent fiber, wood, or metal container specifically designed to carry ammunition. This carrier must provide sufficient cartridge separation.
It would suck to have to dispose of good ammo because it cant be transported to there requirements. And good luck finding ammo then you get there too!:tumbleweed:
