From what I have seen in my research, Clinton House might be the best bet as has already been suggested. I have never been there myself, but the photos and such look like it is a seriously well-kept place. Unfortunately their website is sadly lacking on any specifics as to their facilities. It states they have a 1000yd range, they do 1 mile about once a month, and they do other pistol, skeet, archery, etc stuff. But zero details as to what they actually have. Like nothing, no number of ranges, lengths, purpose, nothing. At least not that I can find.
Anyway, it looks to be about 1.5 hours away from you, and 2 hours away from me. It is probably the closest to you with that kind of length, and definitely the closest to me. I plan to go check it out sometime this year myself.
