Welcome neighbor. I'm relatively new to Pickens County. The only place I know of is the DNR range in Pickens off Brazealle Rd. It's limited to 100 yards and yes, it's a bit restrictive.
I got a membership over in Elberton GA (sixty something miles) to be able to reach out to 400. If you find something closer, by all means let me know.
Looking for backwoods places to shoot in Pickens or Oconee counties. The gun ranges suck...too restrictive and distracting for teaching.
