I'm only 30 miles from you, up in Cleveland. The local gun dealers that I know of have a meager selection of muzzleloader stuff, if any at all. Sportsman's Warehouse has a little bit stashed back in a corner. I think that is in East Ridge. There isn't much around here. When I need something, if I can't make it myself, then I generally order it from one of the main companies on-line.
Only yesterday I made the rounds of Sportsman's Warehouse, Bass Pro, and several local shops looking for a .480 round ball mold. Nothing! I have to order it.
