    Just remember that 1 mil represents 3.6" at 100 yards.
    So lets say that drops are:
    300 yards = 7"
    400 yards =22"
    500 yards = 45"

    For 300 yards 3.6 x 3 = 10.8 (this is what 1 mil represents at 300 yards) Now take your 7" of drop for 300 and divide it 10.8 and you come up with .648 mils for your hold over.

    400 yards 3.6 x 4 = 14.4 (22 divided by 14.4) = 1.529 mil hold over

    500 yards 3.6 x 5 = 18 (45 divided by 18) = 2.5 mil hold over

    I hope this helps

    nate this will work for any caliber. If you have your drops just substitute them for the ones for the corresponding yardage. Do you have your drop chart?

    why spend 30 buck when you can spend 30 min doing a little math and make your own drop chart and tape it to your stock?

    One more ? if im shooting 200 yrds at a 2 deg downhill angle
    and did my math this way
    11.27* .999=11.258
    4.43-11.258=-6.82
    3.6*200=7.2
    -6.82/7.2=-.94
    so that means i would aim .94 mills low at 200 yrds or am i doing this wrong?

    better yet, spend $75 for Exbal with the reticle calculator tool and you can figure drops for any scope first or second focal plane with any caliber.
