Well biganimal, I'm not from SC but I'm from the next best thing. I was in Myrtle Beach this summer. Just south of Myrtle is Murrell's Inlet. There is an indoor range and gunshop called Coastal Sports. Its pretty nice, though I don't know if you can shoot rifles. It has a 25 yd. air conditioned range. The gunshop stocks some nice pistols including quite a few Wilson 1911's. It's worth stopping in.
