I’ve shot on their 1000yd rifle range and shot several DMR style matches there
A friend with a spotting scope definitely helps. I think the closest target on the 1000yd bay is 400yds and on out to 1000yds with MOA targets for each distance and a larger target beside it and they have a 100-200-300yd range as well. I think they do Mile days with the 1760yd target on occasion
The “road” down to the 1000yd shooting platform is pretty rough and rutted and downhill to the platform. If it’s rained recently, you either need speed or 4x4 to get back up it.
Here’s a picture from I think 3-4 years ago holding at 1K:

I’d been killing the 800-1000yd targets with my 224 Valkyrie back when I had it
I only live about 45 mins away…it’s fun as a guest but I don’t know if it’s worth joining IMO
