I only know of two. Blue ridge mountain men and Muscogee long rifles. One up around gainsville and the other columbus ga. Both 1/2-2 hours. If you are just looking for a range there are several close. stop by Deer Creek close to downtown marietta. ALL old school stuff. Lots of muzzleloading equip. Does not cater to modern firearms at all. They got a Pedersoli 45 long rifle flintlock on the wall $525. Bought the only place to buy real black as well. He has got handmade bags, horns, flints, accessories wall, barrels etc. you can spend a couple of hours in there easy. hours are 9-6 tuesday through friday and Sat am. Family run three generations.
Hope this helps. What are you looking for in terms of ranges?
