I went and it was lretty good. Not quite Chantilly, but close. They had several crates of mosins and one of sks's. Tried to buy a beautiful 91/30, but my drivers license had expired 2 days before on my birthday. I was pretty upset as you could imagine. Crates of ammo too. My son (I) bought a single 50bmg (for him) from a vendor for $3. Also bought a nice crosman vantage air rifle since I couldnt get the mosin.
I went Sunday. I was interested in a rifle but they would not sell it to md residents (bolt action). There was a bunch of ammo though. The guy with cheaper p-mags sold out quickly. I got a few odds and ends. It definately was not chantilly or Fredericksburg but not too bad of a show.
