    I get around 245 w/ OT2, which is probably close if you are shooting mid 60's in weight. I plugged 65#'s in for a draw-weight, and based it off of 29."

    More info yields more specific responses.

    If those numbers you posted are correct and you use the same chrono... ten bucks says you are shooting within 2 fps of 235. IfI had to pick a numberI would say 236.
