Paper tune after the initial setup. I'll say it again, paper tune after your initial setup. I use Montec 100 and 125 gr for huntingand same arrows with 100 and 125 gr field points for practicing. The Montec's will fly to the exact same spot at the field points as long as the bow is in tune. If it's not in tune they won't hit the spot. Not just Montec's, but any fixed blade
head. You can be way out of tune and get damn good groups with field points and believe that you've got a great shooting bow. People do it for years and never have any idea that their bow has never really been in tune. Bear shafts will fly the same too, as long as the bow is in tune. If you don't know how, have your bow shop help you, or go to one that does know and will help. You won't be sorry.
