RE: Tuning Question
A picture would be really nice, but I'm going to bet your shooting form is the main fault here. Your pin is up and your sight is up. That usually means that your anchor is too low and the string peep and/or kisser button is too high above the nocking point.
Take this as a suggestion, but you probably need to lower the string peep and kisser (if you use one). How much? Whatever it takes. It's dependent on the angle of the string and other factors.
To accomplish this and maintain string contact references (touching nose?) you may have to shorten the draw length of the bow accordingly. This is usually the thing most guys don't want to do because they are either hard headed or don't want to give up any speed. Regardless you do what you have to do to make things fit. That's why most bows are adjustable in the first place.
Again, ths is only an educated guess as to the problem. Without a picture I can't confirm it.
