One of the only places I know of would be Quantico Base. There you can shoot out to 1000 yards. But first, you have to join their Rod & Gun club (normally a waiting list), then, have all your firearms inspected that you want to shoot (limit of 3 firearms inspection per visit), then wait till you find a Rangemaster who 'feels' like opening the range. I found it more of a PITA than there was benefit. You can also check into the Issiac Walton league. I've heard they have several ranges but I don't know distances or what their future might be. There is a private club in NVA that offers shooting out to 300 yards, but membership is expensive and there's always a waiting list for membership as well.
