oh i forgot to say the arrows are full length still as i draw around 29.5 to 30.5

[**DONOTDELETE**]

how many arrows do you have? Take one and cut 1/4" off, replace point and shot it. If that doesn't work. change brace hight, little at a time and shot after every change. Also try padding out your window some. all these things must be done one at a time.

Also what handed shooter are you?

sorry i'm right handed i will give that a try thanks
i just made a new string for the bow so i will shoot it in a bit and brace it properly
