Fellas i need to build a heavy duty target stand for my range. My wooden backer is wearing out, so the next one i build needs to be made with a steel frame. I have some ideas, but i thought i might see what you fellas have done or seen? I would like to make this backer to be able to slip it in or out of a base system at ground grade. Tube inside of tube, or something similar. Needs to have some weight and ridgitity. Wind blows pretty heavy out here! Any thoughts? I priced some steel this afternoon. All i can say about that is, OUCH!!!!! Lee
