Things are not that simple. Can you go to a 150 gr snuffer or change arrow size because the bow is too strong? Can you change broad heads?
I sent you an E mail with what I found. Hope you get it all. Paper tune, then tune for a broad head, But no broad head will go to a bare shaft and no broad head will go to a field point unless you do what I do. I make any broad head go to the field point.
Everything you stick on the end of an arrow will alter where it hits.
I hope you can make use of the stuff, Easton stole it. I made the mistake of sending it out and some found I was right and took it.
Nobody has ever made a revolver shoot like I do or a ML either. Or a broad head from a bow. Hard work and many years.
