There are also two small shows South of Harrisburg this weekend, that may be worth stopping by on the way up to Harrisburg. These are probably better for those looking for older stuff, instead of the run of the mill big gun show stuff.
This one is about 5 miles East of Rt. 15, this one is also open on Sunday,

I. The Harrisburg show is great if you want AR's or new guns. It had lots of guns and some had reasonable prices. The guy selling powder at the far end was five bucks cheaper than Bass Pro so that was a good deal. A guy in the middle had Hogdon HP38, Blue Dot and Green Dot for $20 a pound. TNT reloading was also there and their prices are pretty good. The milsurps and hunting guns were pretty high.
I had a different experience than TargetGrade at Dillsburg. I found several kinds of Hornady personal protection ammo for $10 a box. One guy had Pryodex RS for $10 a pound. Another guy had Pryodex P for $17 a pound. It was still sealed and good. I found a Winchester 94, pre '64 for $375. There were some really nice deals to be had at Dillsburg.
