I need some help from anyone who knows how to score the........."USRA-IR50/50 targets and the green, IBS Rimfire 50 yard Targets" I am getting different ways to do this from shooters and even rule books. Most are saying, "The bullet hole that touches the line receives the hightest point" What gets me is the GREEN IBS 50 target has a 10 ring of 1/2". This is the same for the 100 yd targets. The USRA-IR50 targets have a 7/16" 10 ring. I am now told the green target, you have to be inside the 10 ring line,not touching the line) to score 10 and for an X, it has to be taken all out.,center dot) Who or what is right????????
