Just want to know if there is anywhere online I can find where the scoring circles are on various 3D targets before I shoot at them. I have shot many tourneys, including the Rhinehart 100 with different clubs and last weekend we were all shooting from the same stake, MBR, MBO, and Hunter class. Is there a limit on bino magnification? Isn't that a bit out of kilter to put someone shooting with scopes and dials and verifiers versus fixed pins and peeps? It would be like someone in a rifle contest shooting open sights versus someone with a 3 by 9 verible scope. Anyhow, just wondering how to know where the 12 rings are on the various 3D's before you shoot at them. Is there a limit on bino magnification? Please help or just tell me to shut up and shoot, thanks.
