I would check a couple things. Is your Bow tuned,and the arrows are all fletched,spined correctly . If all are yes then what you need to do is mark you arrows, I use a permant marker and shoot your group If the same arrows flair everytime. then get rid of them or re fletch them.You may havesomebent or scraped arrows.If those check out. then check at your form You may be grapping the grip or adding some torq some where. You may even be punching the trigger on your release. If you shoot fingers your could be plucking the string and not getting a smoth release. It could be a number of thingsbut that will get you started in the right direction.
