You need to get your bow properly tuned.
First step, make sure the DL is correct for YOU.
2nd, make sure your grip is correct. Knuckles of bow hand should be at a 45* angle off the grip with them really lookin like this /. DONT grip grip the bow, you really want a relaxed grip like this
Third. Check the bows ata and brace height measurements. Make sure they are close, most of the time they are gonna be a touch off, but make sure they are close.
4, check the bows poundage, that's usually a result of the ata. If that's correct poundage should be good.
5, make sure the cams are both in time and synced up. If it's a hybrid cam system make sure they hit the same time or the head just touching a hair before the bottom
Single cam if the ata and brace are right, cam should be rotating over in the designed rotation from the engineers.
Binary, hit at the same exact time.
6, set center shot. Set arrow level through the Berger hole, or just a touch of Nock high. But usually not to much on any now.
7, set the rest with the arrow so the center of the arrow is 3/4" or 13/16" away from the riser.
8, check the bows top cam lean. On hybrids I usually set a little pre lean to lean the cam a touch left utilizing the yokes.
9, now you need to make sure your arrows are properly spine indexed. If they are a stiffer spine then recommended, that's fine. You CANT be weak.
Usually if someone shoots 70-60lbs I'd go 300 or 340 spine. 60-50 probably 330-400 spine. That way your always in the right range or a little stiff.
10, get 1 fletched arrow with a field point, and 1 arrow with a field point with no fletchings. That's a bare shaft. Shoot the bow at 10 yards. See if they hit the same point and the bare shaft is entering the target perfectly straight. If not that means you probably either need to mess with the DL, grip, or the arrow rest
11, once bare shafts hit together with field points at 10 yards, go back to 20 yards. If they hit together, with the bare shaft directly straight in the target, your bow is properly tuned.
******note of your arrows aren't fletched with the stiffest part of the arrow on top, where the cock vane goes you may also experience some arrow flight problems. Best way to fix this is strip all the arrows vanes off, then shoot all bare shafts through paper rotating the nock in the arrow until you get a perfect bullet hole for every arrow.
Also, you have to admit to yourself your DL is long or short if you can't yoke tune, move the rest or change grip to get the bare shafts to hit together. The right DL is key to optimal shooting and accuracy, and optimal arrow flight.
If you get bare shafts together with fletched at 20 yards, you should pretty much be able to shoot any broadhead on your arrow accurately, with the poi as fletched.
