You can try PSC. They're in Friendswood (a little outside houston), but I believe they allow what you are looking to do. It's a private range and membership I believe is mandatory or you can show up with a friend who has a membership.

Edit: Oops, I see you said "Public" range. Sorry, I haven't seen any public ones that allow this.
