I've had a Fred Bear Code now for going on a year and it shoots great. the only thing is as I go to 30 yards and beyond, the arrows begin to drop alot. I'm talking 6 inches from around 20 yards to around 30 yards. this doesn't make sense bcuse it is shooting what many would consider fast. I have a drop away rest and Easton axis arrows and as far as I know there is no contact between the arrow and the bow or rest. does anyone have any ideas on how to fix this?
