Abstract
The system is for use on outdoor firing ranges. Target cards bearing the printed targets are secured to a 4 ft. square panel made of Coroplast (trademark), which is extruded twin-walled polypropylene sheet. The sheet is formed with built-in curvature, which is sufficient to render the target panel rigid, even though the material is thin enough that bullets can pass through without punching-out. Because of the curvature, no frame is required to keep the panel rigid. Scoring rings are printed on the face of the panel, together with a centering device which comprises markings that allow an attendant to align fresh target cards with the scoring rings. Two or three plies of Coroplast may be welded/glued face to face, for larger targets.
