Bare arrow question

[voz]

Trying to tune my bow, shot two arrows with fletching, two with out. The fletched arrows, I was aiming low...bare shafts aiming high. My question is why are the bare shaftsgoing into the target at an angle? And how do I fix it? I only have 1 pic small enough to post

Assuming the target's not the issue, I suspect center shot is not set correctly, too far to the left, perhaps? No fletch so the arrow can't correct it's flight. The fletched ones are.

If I were you, I'd fling the bare shafts through paper and adjust center shot until I get a perfect tear, then shoot again to see what's up. From there, you can group tune if that's your thing...
