RE: arror grouping
I had similar problem i could shoot great out to 25 yards but could not hit at 30 . I discoverd it was my follow through after the shot . I use a wb rest so it is more important to have a good follow through since the arrow is in contact with the rest for a longer period if time. if you drop your hand after the shot or torque it a little your shot will be affected and mor noticable at longer distances
