For organized range, Clark Brothers in Warrenton, however, I'm reading into your thread that you miss stepping out the back door. Look up "The Cove" campgrounds in Gore Virginia... Basic directions are north on 66 towards Winchester, then the bypass, around to route 50 west, and from there about 15 to 20 minutes til you're 4 miles from the WV border. You check in at the office, pay your 12 bucks and follow the directions to the Rifle Range. Its about a mile back around and up top of a mountain. Your average "To-from commuter car" might have some difficulty negotiating the dirt path, but Pick-em up trucks and my Jeep Commander have no problem at all.
There are three berms set up, one about 25 yards, on the left another about 50 yards on the right and straight ahead and into the mountain an alley about 120 yards long. Folks have targets set up at various ranges, as well as old computer terminals, bowling pins, just about anything you desire to plink at.
My son and I love going to The Cove, but it is a purty good hike for us coming from D.C area.
