Closest matches will most likely be on the east side of Memphis at the Memphis Sport Shooting Association. According to their website, they have USPSA, Cowboy Action, IDPA, Sporting Clays, Skeet, Trap, Bullseye, High Power Rifle, Steel Challenge, and others. Website is here: http://www.memphis-ssa.com/
There are some type of matches near Corinth, if you want to stay in state. There is also IDPA in Saltillo. I'm guessing that would be between an hour and hour and a half for you to drive.
