    Im trying to tune my bow cause I haven't been able to get my broadheads to fly very well. I tried paper tuning first and at about 6 feet I could get very close to a perfect bullet hole but not exact, at about 20 feet I have perfect bullet holes. I then took my bow out to 20 yards and shot it and it shot off about 6-8 right. So Should I move my sights or is this a bad thing? Did I paper tune it right or wrong? I followed the directions in the Easton Arrow Tuning Guide. Any suggestions would be appriciated. I have pictures of the paper but im not to sure how to attach them.

    Paper is a good start and at 6 ft it sounds good. 20 ft the fletching has time to straighten the arrow out so it should be bullet holes. Go ahead and adjust your sight and once that is done try broadhead tuning and see where you stand.

    Several things can happen with paper.Cam lean ,spine issues,fletch contact,hand torque,facial torque can all cause a tear.

    As you can see,there is alot more to paper tuning than adjusting a rest. I actually don't think you should move a rest to get a good tear.

    Eliminate fletch contact. Move to french tune to set centershot. Then broadhead tune. If the broadheads won't come into field points,then you most likely have a spine issue.

    If broadheads come together with field points,recheck paper. If there is still a tear,you most likely need to yoke tune(adjust cam lean out) or work on your grip.

    Work back and forth until you get a good tear and broadheads and field points are together.

    French tune is just setting centershot by shooting the bow.Make a vertical line on the target with a carpenter level.Shoot at the line from a couple feet away. Adjust pins so arrow impacts line. Move back to a comfortable distance.Further the better but it can be done at 20 yards. Shoot at the same line. If you impact left or right,move REST until arrow impacts line. Repeat until you hit both line at both distances.

    Yoke tune is twisting the split cables until there is no cam lean.The lean is caused by the offset cable guard.Usually a couple twist can make a big difference.

    Look up on how to do a walkback tune. Then I would try to paper tune.
