Thinking about a portable target stand for use at a friends place. The idea I had is a PVC frame with a couple big truck mud flaps hanging to staple paper targets to. I like the idea of mud flaps since I can pick these up for free. Needs to be movable so we can drag it out of the way when not in use. Anyone built something like this? Or can give me some advice. PS primarily for 22 & 223 at 100 yards. Maybe a little pistol or larger rifle occasionally.
