First show since moving to TX, so I can't say how good it is compared to others in the area. Wasn't as big as the one I was used to going to Costa Mesa, CA, but I still enjoyed snooping around.
If you're looking for powder and primers, don't bother with the Fort Worth show. The city won't allow those nasty items at the show. I've been to the Dallas show twice...always a good one.
There are two shows that cycle through Fort Worth. "The Original Fort Worth Gun Show" and the "High Caliber Guns show" IME the Original is the better of the two, but the big vendors show at both. This weekend it's the High Caliber show. It will still be a pretty big show. If you're looking for ammo, look for the Georgia Arms booth if they are there. Really good ammo and reasonable prices. The last show a couple of weeks ago was the first time I've seen them there.. I've bought from them on line, and and when I saw they had a really big booth, I bought a 500 round can of 9mm... If I remember correctly it was about $115 which included the ammo can. It's much better ammo than WWB or the cheap stuff from W/M.
