Don' t know what bow you have, but keep in mind that the " string to nose" reference point can be harder to obtain on shorter ATA bows...

I just set my no-peep to where my body goes naturally and comfortably, and it' s all good

1. Kisser button to corner of mouth
2. String to tip of nose
3. Knuckle of release hand behind jaw bone

Fletching in corner of mouth
Large knuckle on release hand at the base of my ear

I went and picked up my bow and got to shoot it while I was there, the anchor on the nose works good, thanks, I can' t figure out how some of you put the fletching in your mouth though. I' m anchoring the string against my nose and am trying to find a reference point for the release against my jaw which is giving me the most trouble. While I was there I tried some new releases but I got the best groups with the one I had so I' ll see if it makes it another year. How often do you guys change them or what' s the normal life span before they start misfiring or do they at all?
By the way my fletchings were touching at 20 yards consistently. I can' t wait to try it out to 30 and 40 yrds, it was too winding to try today. Rangeball, I have a parker hunter mag it' s now set at 32" 67# with carbon force 300 arrows 30" long with 100 grain heads,
What would be the kenetic energy of this set up? It was shooting 272 fps but I don' t know now. Sorry for all the questions I' m still learning
