Did you purchase to bow new or used/ private sale or from an actual archery shop? Buying a bow is similar to buying glasses, its hard to pick one up and have it work for you the way you want. Sounds to me like peep placement and draw length might be the issue usually the rest is the last thing I personally would adjust. That has a significant effect on arrow flight ( more noticeable with broad heads).That being said I would take it in to an actual bow shop have them set it up right for you and shoot it through paper. Hope this helps
