I just refletched my arrows with NAP's Quickfletch. They look awesome but I am having some issues. I cannot get a consistent pattern. There is always one arrow that wanders out of my group. I am trying to get a pattern at 20 yards. Any suggestions?
You should mark the arrow that is wondering off on you and see if it's the same arrow each time. If not than it could be something your doing.
Like jay said number all your arrows and without looking at the numbers when you are shooting see if its the same arrow that is outside the group. if so try rotating the nock 180 if that doesn't help that arrow is most likely spined differently compared to the rest.
Let's start at the simplest fix... Are you sure your nocks are all rotated properly and you have adequate fletch clearance?
