Dont forget your string is going to stretch big time so at first don't worry if your hitting the bulls eye. just get it to hit paper and then put about a 100 arrows threw it. then the next day sight it in and do it again then if it holds the point your good but it'll probably move a bit again. after your sighted in with your field points shoot some broad heads see if they fly the same this may need tweeking . that said have fun
