Pooner,
There is a range near Corinne called Salt Creek 3-D range. I make trips up there from Bountiful regularly. Some of the targets are hammered (or were a couple weeks ago when I went), but they still work and there are some tough and realistic shots to take.
Also, you can shoot at the range up by Mantua, but they are bags not "life form" targets.
Good luck.
