Jeff or Ngoc will correct me if I'm wrong about the .50 issue, but in summer's heat an indoor alternative might be Shiloh (http://shilohshooting.net/). They're just east of Willowbrook Mall off Highway 6, air conditioned (actually, a very good air-handling system; no feeling you're inhaling fumes), pistol bays out to 75 feet and, well, just a very neat facility the Sanford family has built. Just don't shoot the target hangers!
