    This sucks. I just spent a couple hours figuring out ranges and clicks for elevation out to 1000 yards, in 25 yard increments, with windage at 5 and 10 mph, printed out a fancy cheat sheet on an index card and proudly taped it on my gun stock. Then I looked at the scope turrets, and they say 1 click = 1 cm/100 meters. Anyone know how to convert the data?

    I was using the free trial version of shoot! software, and the load was a 7 STW, factory 140 grain ballistic silvertip at 3300 fps, 5 feet of elevation, 80 degrees F, 78% humidity.

    I have a conversion chart and I did some quick figures (I could easily be wrong) If you have .25 inch per 100 yard clicks on your chart and have 1 cm per 100 m on your scope, then you multiply the chart figure by .6944 to obtain the proper conversion.
    here are the critical conversions for your problem
    Multiply by To obtain
    inches 2.540 Cm
    inches 25.4 MM
    cm 0.3937 inches
    meters 1.094 yards
    Yards 0.9144 Meters

    good luck

    Crop Damage,

    Man! That’s a tough one.

    1 click = 1cm @ 100 m
    Then:
    1click = 0.3937” @ 109.3613 yds.
    Then:
    1 click = 0.3600” @ 100 Yards

    Let’s say at 300 yards your bullet hits 8 inches low. Now all you have to do is (8/3.00/0.36) = 7.40 then GO UP 7 CLICKS!

    If at 380 yards you need to correct for 18.87” low; just do this: 18.87/3.80/0.36 = 13.79, I would go UP 14 CLICKS.

    Notice that we are using the distance divided by 100. 380/100 = 3.80

    I hope it helps.

    Crop Damage,

    How does the turret look like, does it have markings like
    longer lines every 10 clicks?

    Thanks a lot yall. A whole lot. That eskimo website is fantastic, it spat out numbers that took me forever to crank out on the calculator. I especially liked that you can print drop in whatever units you want, like 1 cm clicks!

    My scope, the zeiss diavari that is on there for now, has a bigger white hash mark every 5th line. I'm not sure if you can reset it to a zero point, there isn't much of a way to tell where you started from if you start turning the knobs. I'll probably put my leupold back on there, its reticle is better suited for longer range shooting.
