Most likely you are seeing vertical dispersion because the string is to the side of your nose. Even with a consistant anchor you will see VD because your head is not in the same place twice.

The correct way is to touch the string to the tip of your nose. It acts as a secondary anchor. With the string beside your nose it allows you subconsiously to tilt your head up or down slightly and differently with each shot.

With the head tilted slightly up the sights will be raised inadvertantly to match your line of sight causing you to shoot slightly high. The next shot with your head tilted slighlty lower will cause the shot to be lower............hence the vertical dispersion.

Sooner or later our heritage of hunting is going to be a rich mans sport and the words "Outfitter" and "Hunt Industry" will be synonymous with cancer and A.I.D.S. among blue collar hunters like me and my family! (A.L. Williams - 2010)
