[QUOTE="varmintH8R, post: 839536, member: 39801"] THAT is an interesting concept and way outside of my technical competence. Most of the POI shifts I have read about using the Magnetospeed were generally attributed to a change in barrel harmonics. To my uneducated mind your theory has merit and I would be interested in what others have to say. I intend to try this Chrony on a bunch of different rifles, and will post any findings on POI change. My intention is primarily to back-check proven loads for ES and get another data point for working out drops. I have seen many claims of POI shifts with no effect on group size, but until I have WAAAAAY more experience with this unit I am not going to use it for load development purposes. It is definitely closer than 5" from the flight path ... Job #1 is quadruple checking my set up so that I don't become "that idiot" who shoots it off:D [/QUOTE]
