Idk how people actually sell anything at gun shows.
There was a gun show in my area this weekend, and with the prices people want for things there it is a miracle anyone buys anything. Garands in not very good shape for $2500. No special attributes or provinces either, just some throat measurements. Even bulk 9 mm and 5.56 was much more expensive than what I could get it for right down the road at a store. I did find one older gentleman selling HXP M2 ball for a reasonable price, which happened to be what I was looking for, so I was able to pick up 120 rounds of it along with a free 7.62mm ammo can he gave me with it, but other than that, no one there was selling .30-06 for under 1.75 a round. I know I should be happy with what I was able to find, and I am, but it is just a little bit ridiculous what people are charging.
