Wanamacher's Show in Oklahoma is what you're looking for.I'm gonna do the old guy thing for a minute, even though I'm not THAT old... way back in the long long ago, around 1990, gun shows were AWESOME. The Gwinnett one that happened at the "Macro" building (a long shuttered store), on Oakbrook Parkway took up the WHOLE BUILDING. Not half of the remaining non-partitioned part. People from middle GA would drive up for it.
Ammo in wood cases, by the pallet. $99 for 1200 rounds of Norinco steel-core 7.62x39mm. $20 for 200 round battle packs of brass-case .308, etc.
But then Clinton ran half (90%?) of the FFLs out of business, and the "assault weapon bill" happened, and Clinton and ilk banned the import of the cheap ammo and a lot of guns, and so forth and so on until I haven't been to one in two years. And haven't bought anything at one in three.
Too bad; I used to like 'em.
One day soon I'll go to one in Texas and see how they are out here.
