CMP is a modern facility, with target cameras and monitors on the benches if I remember what my friends said, I've never shot at a range like that, but it would definitely be a time saver when dialing in a rifle. Not sure if the Lexington range is that modern ?
Arena Training Facility in Blakely GA is outstanding. It’s a 4,000 acre facility with a myriad of different training venues; KD ranges, pistol ranges, breaching facility, multi-purpose ranges, shoot house, etc. It is not an open range, and they don’t have memberships, but they hold open shoots several times a year on their 2500yd range. They also host a wide array of competitions and some classes. I teach classes there 2-4 times a year.
Elk River Training Center in Pelham TN has a 1,000yd range. It is open to the public and they have memberships. I teach a 2-day Basic Precision Rifle Course there a few times a year. I take you from nothing to 1,000yds. Next course is in mid-April.
SCOTG In Laurens SC has around 1,500yds. I heard they have made quite a few improvements lately. It was a nice facility last time I shot there.
I have access to 400yds on private property outside of Cartersville. I’m running a mini-version of my 1,000yd course there, the next one is in May. This range is not open to the public.
I’ve heard that it has new owners since the old ones invited me over to teach. I have not confirmed this. My only complaints about the place was the small firing line and the provided steel targets are every 200yds. I’ve been told that they’ve greatly expanded the firing line; no idea about the available target distances. When I was there last, they did have multiple targets at every distance; 5 or so IIRC.
