It's mostly yahoos shooting pistol all the way up to the berm these days. If you get lucky, or go out early enough its a good spot. Oh and last time I was out at DSRPC one of the workers was showing a couple guy on range 9 where the 1000 yard target was. I guess it's not a secret. I've been looking for it in the wrong spot all this time haha.
Haven't been in a while, but this is an easy to get to spot if it's still ok to shoot there...
