Used to be able to buy IPSC targets on about 3/16" styrofoam sheets, approximate size 22" x 34" . These last forever and make great target backers when suspended on a pvc frame with some elastic cord. Anyone know where I can get some? I had a couple of them on frames, with the A zones shot out with about 75 rounds in each, printed on the bottom in 4" heavy black letters was "SHOULD YOU REALLY BE HERE?" --- Great deterrent signs to leave on your property where you don't need any intruders.
