Challenge targets have concentric scoring rings calibrated to your caliber and distance. Find the smallest ring containing every shot for a centred-containment score in MOA or MIL. The score combines dispersion with group-centre offset from the point of aim; it is not a direct center-to-center extreme-spread measurement. Ring diameters include bullet-diameter correction.
Challenge targets are used for quick benchmarking, NRL22 and PRS practice formats, and tracking precision over time. 37 calibers, any distance. Free PDF download.
