There is one near Amherstburg. Here is a link ... http://www.amherstburgtargetsports.com/
The Amherstburg club is also in the process of making a permanent 5-stand setup. Should be pretty good. I used to shoot there when it was just a temporary 5-stand, will definately start going back again now. Windsor has a pretty nice skett range, but like previous post stated, the curtain posts are being repaired at the moment. They are also currently going through noise testing to have a rifle range put in. Firearms people already gave them ok to put one in.
Windsor Sportsmen's Club trap and skeet fields should be open hopefully by Sat. July 9, maybe sooner. Call the Club at 519 966-1600 for details. The proposed rifle range will feature a 25 m, 50m and 100m for .22, centerfire and muzzle loader.
