Public land to shoot on Lewisville/Ray Bob/Ray Hubbard?

Need to take my dog out to work on gun noise - is there anywhere on any of these lakes or other land I can take him and shoot a shotgun?

I think there is public land in the 380 Greenbelt, owned by Denton County. I know people go there and hunt feral hogs. Just don't have contact information for you.

Ray Roberts Type II permit, although "target shooting/practice" isn't allowed if you are legally licensed up and permit you may give it a shot, lot's of ground there. I would pay particular attention on whether steel shot and duck stamp needed since waterfowl season is on. If steel/duck stamp not needed who can say you aren't squirrel hunting....
