I am a member and have been there several times, don't go as much as I would like as for me it is about an hour drive or so, good range, they have been working on a lot of improvements lately, they have steel to shoot on the pistol range, rifle range is nice, goes out to I believe 200 yards, also have a place for shot gun patterning and an area for archery
Some things have changed in the 10 years or so I've been a member, but it's a good outdoor range that allows a lot more freedom than just about anywhere in MD. It's private, but cheap and easy to join, just show up to a meeting, and they vote you in. I live close so It's easy to run by and put a box of ammo through a gun, practice or test what I need to, even still don't get to go as often as I'd like. They have put up a fair amount of steel on the handgun range, and a few plates on the rifle range. There are somewhere around 1,000 members, but the range is often empty being most members rarely use it.
