This isn't the biggest gun show but it had enough to be interesting.
I inadvertently snuck into the wrong line and got a Dealer hand stamp initially. Amusing.
Finally found the right line and paid the admission!
Ammo could be had even .22LR but prices are still high.
The did have a cannon dealer! Prices ranged from $650 to $2800. No special permits required in VA, for cannons or mortars. they don't even call in a background check because it is a muzzle loader. Plenty of cannon fuse available too!
