    Bareshaft and Spine Selection

    Can any one give an educated guess (or prefarably know for sure) how far to the left, or right, will a bare shaft land in relation to a perfectly matched arrow, per spine difference, say at 20 yards?

    John.
    Won't it vary according to setup?

    Rik,
    I donít know, but I (perhaps mistakenly) thought that it would be a consistent measurement as long as each spine of arrow was shot from the same bow.
    Are you saying that some set-ups will shoot a wider range of spines in tighter groups than other set-ups?
    John.

    it would proably be consistent if all other factors were identical. If the bow were set in a machine similar to those available for compounds, but there are too many variables with a human (or at least there are with me)

    sorry mate but the bare shaft is not for tuning, as such, but as a check once completed. the misconception comes from a rick mckinny interview many years ago when he said his bare shaft goes low left, that is personnel to him. once you have set and tuned your bow, shoot a bare shaft, remember were it goes and then it can be used for quick reference if you change something. hope this helps
