The courses can vary. Natinonally there may be (2) 20 target courses (40 targets total) or (2) 10 target courses and (1) 20 target course. The max score for a 40 target event is 440 points. If you shoot a local event they may only have 30 targets. Usually they are devide into (3) 10 target courses or (2) 15 target cources. And then there are clubs that only have (1) course, 30 targets.I hope this helps. I have been shooting 3-D for 10 years and have enjoyed every minute. Good luck and hope to see on a 3-D course.
