Fieldcraft Windage Chart

Re: Windage Chart

It's handy to make one which looks like the one below. The columns across the top are wind speed in mph. The rows are distances in yards. That way, you can interpolate between both speeds and distances. The wind holds are in mils.

Re: Windage Chart

Kinda sorta.

I used a ballistics program for my load to develop a set of constants for the equation:
<div class="ubbcode-block"><div class="ubbcode-header">Code:</div><div class="ubbcode-body ubbcode-pre" ><pre>
range(yards)/100 * windspeed(mph)
wind hold (mils) = -----------------------------------
constant
</pre></div></div>

I used the constants thus developed to program an Excel spreadsheet.

It's not perfectly accurate, of course, as it will change a bit with temperature at long distances. However, my ability to call the wind to a mph or so is not perfectly accurate, either.

It's a place to start, and displayed in that form, it allows me to make an educated guess on gusts.
