The Challenge Cup is one of many shooting opportunities available at the Southern SxS. To amplify Tom's comment about the qualifying round (50 targets), 2/3 of the targets are REPORT PAIRS. The other 1/3 are TRUE PAIRS. These 50 targets are on a 5-stand layout with 7 or 8 traps, but you shoot 5 PAIRS at each of the 5 stands. It goes pretty quickly. There is plenty of time for visiting the huge tented gun show, and shooting the myriad events on the Sporting Clays course.
