Stonewall isn't bad. 300y, though only flat out to about 200y. They used to have some target frames made out of old well casing. Of course, thanks to people not caring about the place, they had to be removed as they had been shot to hell.
A salesman over at McFly's had claimed a few customers had complained of small stuff (binos, rangefinder, etc) getting stolen there, but I've never seen or heard of it from anyone else.
If you're ok going a little further, White Horse is excellent. They have a free range that's 100y and it's well cared for, but they have specific hours. I think noon to 5pm in the fall/winter. Haven't been a member there in a few years. $60/yr gets you access to the 600y range, with 1000y days a few times per month, though that sounds like more than you're looking for.
