I went to the Saxet gun show last Saturday in Conroe, TX and it was packed the most I've ever seen (est 2k+ in attendance at peak times). Usually there are about a dozen or more dealers selling ammo typically before the rush to stock ammo began. This time there was only 1 large dealer and their table / supply had been wiped clean by noon time when I got there.
There is another gun show this coming weekend about 65 miles across town and I intend to be there when the doors open with crossed fingers.
At our gun shows, I work the Virginia Citizens Defense League table. I show up an hour before the public is let in and I do my shopping. Work the shows it pays off getting what you want. I also get better discounts at the tables wearing the badge from the VCDL table.
