An inexpensive rifle range is the Clinton WMA. You just need a hunting license or go with someone who has a hunting license. Any caliber up to .30 is allowed.
I used to be a member at SCFGPA, but we had a falling out. Nice range, but very restricted by their fear of law suits.
I’ve been a member for a few years now. Ya gotta get on the mailing list and wait for membership to open. Apparently they just sent out about 80 letters. If you’re retired this is a great club to visit during the weekdays.
