This is a standard IBS/NBRSA "Group" target. The center of the target is call a "Moth Ball", the lower target is a "Sighter" target, and it has 3 "moth" balls, the upper target is the "Record" target, and it is what you will be scored on. The target is designed for diferent sighting positions. The rings are there as a reference point for hold positions. If the gun is printing dead center of the moth ball, and the wind changes, you can go down to the sighter target and see on what ring/s you need to hold on to get the bullet to impact back into the center of the moth ball, then when you go up to the record target you can find that same hold position. Some people prefer to section off the black box at the top, sometimes called the "Top Hat." Some people may line their cross hairs so that they "Corner off" the box. (Place the top of the cross hair along the bottom of the box, and the upper right vertical cross hair against the left side of the box, and have the target pring just below. In group shooting it dont matter where the group is at on the target, as long as it is in the sectioned off box, that houses the rings, and the box. There is no bulseye, as shooters dont want anything that can affect the view of the bullet imprint.
