I have never been to a gun show where you could shoot. Don't know that I would unless it was a private range and only for members.
The show in my town is getting pretty big. Actually, there is one this weekend. There are lots of guns, ammo, relaoding supplies, knives, holsters, you name it. There are some "okay" deals but not a lot. Components (if you load) seem to be priced the best compared to everything else.
Also, you can expect lots of old guys that feel they need to save their s for this event and release them throughout the facility.
It's usually just overcrowded and overpriced.
