We just got done resetting up my Xt at Robs. We used his laser setup tool and had to move the rest so far in it had to be cuttoff a little on the right hand prong.(Shakey Hunter) I had previously paper tuned it and it was perfect holes. I think that 13/16th is a starting point for sure cause mine is11/16th now. I shoot the Blazers and they clear everything fine, they are close but still clear.
