Far as Alamo Ammo, I know the guys that run Hex Tactical, they had a booth, when the show opened it was a mad dash to Alamo Ammo and a long line!
They weren't in line for Alamo Ammo's ammo, they were in line for the powders/primers/bullets in the booths right next to them in my opinion.
That place makes Cheaper than Dirt look good.
