That's interesting, I was at a show yesterday and got lucky enough to score a 45-70 for a decent price.
But, it was a big show for my area, covered 2 floors at a local high school, gym, another 1/2 BB court, cafetieria and down/around the hallways. I'd guesstamate 5-600 tables. Bout' half the tables fishing stuff, knifes and novelty's.
Anyway's, there was maybe 6-8 shotguns and ONLY 2 SB2 rifles in the whole place! I worked that entire show, looked at every gun rack and table, really. I had to take a lunch break then go back.
Black guns and tactical stuff seemed to be predominate. Primers where back and only slightly higher than the local shops, 35 per K. Got some powder @ $23-24 per# and some bullets. No super bargins, but reasonable gun show costs and available.
