Zeroing with Wind

I personally would wait for a clear flat day to zero. From there it would be easier to figure out the wind to hit your target. I think you'd be fighting yourself any other way.
To be able to read, calculate, and shoot in wind is a science all in itself.

^this. Quarter value, half and full value (90 degrees to the objective) all require different ballistic calculations. There are formulas online if you dig for them, but the big trick is READING the wind direction and velocity. I used trickled sand to gauge it, but I'd done it once or twice
The calculations also change as range increases and decreases. Wait for a calm day to zero your scope. Go stick your roach in Lisa's skivvie drawer

Yeah, doesn't make sense on a windy day. Just wanted to make the best of it i guess. I'll take a different rifle.

At least I'll get a chance to do some Kentucky windage and moa adjustments practice.

Formula is

Wind Speed x distance in 100's of yards = MOA
constant

O-500 yards constant is 15
600 14
700 13
800 13
900 12
1000 11

Thanks Bob.
