Arrowguy,

I got the test out of the Easton Arrow Tuning guide. You can find the guide right on the front page at the Beman.com arrows website.

The way I did it was: Place one strip of masking tape horizontally across the top edge of my target and a second vertically along the right edge. Stand back about 10 to 12 yards and shoot about 6 arrows across the horizontal. I aimed at the tape. (Of course if, your sights are set to 20 yards, your arrows will hit high.) Now just check to see how well they line up. If your nocking point is good, you'll have a nice even row of arrows. If not, make a very small adjustment to your nocking point either up or down (I simply raised/lowered my rest). Shoot the arrows again and see if the row tightens up. If it gets worse, go the other way with your nocking point. Once you have a good row, shoot the vertical line. Your looking for a nice straight vertical row of arrows. If their off, move the rest in small increments either right or left until it tightens up. You can also try adjusting the spring tension to try to fix the vertical.
