When I moved out to Temecula in 1997, I was told that there was an indoor range here in town. I was never able to find it and then heard rumors that it had closed down due to insurance reasons. I belong to range in Rainbow which is only a few miles south of Temecula. It is near the Border Patrol checkpoint off of Rainbow Valley road. Membership dues are $100 for the year and they have several ranges available for different types of firearms. The maximum distance is only 150 yards but this will let you work on basic shooting skills. The different ranges include the following: .22 rimfire, rifle (50,75, and 100 yards), pistol(15,25, and 50 yards), falling plates for pistols(lead only rounds), shotgun (clay pigeon thrower), a set of 3 metal plates to practice multiple-target, close quarter engagements(lead only pistol and shotguns).
You can contact the range at 760-723-8743.
