    I am trying to arrive at a b.c. number for a new bullet and I am not sure how to get it to match my drops.

    bullet: Matrix .264/ 160gr vld
    velocity: 2965fps
    elevation:5300'
    station pressure:24.6
    temp:38 degrees
    sight height:1.9"
    drops: 100yds-0
    300yds-7.5"
    600yds-55"
    1030yds-22moa

    The 100,300,600yd numbers are measured from the center of 3 shot groups shot on one target. The 1030yd number is a measured distance but the impact is close estimate on a rock. It could be a bit off.

    If any number crunchers want to give it a go I would appreciate it.
    Thanks
    Cliff

    Where did you find 160gr .264 matrix bullets? They only go up to 140gr on their web page.
