I am going up in the morning, sometimes at this show there is a powder/bullet dealer that has lots of powder for sale. Prices are OK, if he is there, I will probably pick up some pistol powders.
The show is at Mason Dixon Auto Auction and will run from 9-3 on Sunday but some vendors will start packing up early. It's a small show but I manage to find stuff I didn't know I need. Today I bought a couple of bore snakes for $10 each and also found a slug barrel for a Rem.1100 LH for $80. Didn't know I needed it till I saw it.
Minuteman Ammo is in the back corner on the right and he had a good selection of power and primers. One vendor had a table full of Yugo M57s and another had about half a dozen Mosins.
