Frank challenged how to dope wind on the fly using moa, and eliminate the math.
I use what I call a base 1 system, I have doped my rifle for wind, specifically how much wind causes a 1 moa shift of impact and at what range.
My numbers are as follows
300yd. 5mph
400yd. 3.5mph
500yd. 3mph
600yd. 2.5mph
700yd. 2mph
800yd. 1.75mph
900yd. 1.5mph
1000yd. 1.25mph
Those exact winds will move point of impact on my rifle 1moa (you have to adjust that to work for you)
Now granted I can't judge wind in half mph or quarter mph intervals so I have to use some "artistic creativity" and yes there is a slight error factor but no more than the error introduced with any system from not judging wind to the exact mph every time,......so i do some averaging and the final product looks like this
300yd. 5mph = 1moa
400-500 3mph = 1moa
600-800. 2mph = 1moa
900-1000. 1 mph = 1moa
use half for half value wind
Maybe not exact but will get hits most the time.
