Thread: Ballistic calculator and wind drift.

    Ballistic calculator and wind drift.

    Ive just been playing around on the winchester ballistics calculator. I put in details for a 95gr .243 ballistic silvertip versus a 150gr .308 silvertip. I whacked up the cross wind to 40mph and just thought it was interesting that the 150gr drifted more, only very slightly and there isnt much in it, but i thought it was the lighter bullets that were more prone to wind drift???

    The geeky answer is that a 95gr .243 has a lower drag (better coefficient) than a 150gr .308 bullet, so drifts less.
    It's weight in relation to calibre that counts.
    If I'm going to be accused of it then it's just as well I did it.
