Are those groups with your broadheads or field tips?

If broadheads, make sure you' re sighted to the point of impact and hunt. Keep practicing and concentrate on your form and over time those groups will shrink.

If field tips, you need to shoot your broadheads, ESPECIALLY if they are fixed heads. Many funky things can and do happen once they are screwed on and flung. The woods is a bad place to learn this.
