i would have to agree with BGfisher. Make sure the arrow has the correct spine for your bow and make sure you have the correct fletching. If you are shooting broadheads, make sure they are aligned with the fletch. If you don't the broadhead will cause the arrow to plain off at the last second. As for the peep...use a peep with a large hole. Also, tie down the peep to the string. Tie on bushing on top of and below the peep. This will stop the peep travel...it did for me.
