I do the same procedure that Buckem mentioned. I paper tune 3, 6, and 12 feet then I group tune to fine tune the process. This has alway worked great for me, just remember that paper tuning is a great starting point although opinions differ. I too have great groups now out to 45yds when I get a bullet hole in paper. I don't understand it either that your broadheads hit the same as your field tips given that much of a tear when your paper tuned. Maybe someone with more experience can chime in on this one.
