Many ways to do this but most isn't even close, if done in the real world. FFP scope used to keep one variable somewhat to a minimum.
Using wind flags. Flag position at 30, 60 or 90 degree angle divided by 4. Rough guess at speed and direction. 60 degree flag = about 15 MPH wind.
Clock method and using full value and half value = worthless when I tried it. Maybe I didn't understand completely but it sucked.
Mirage reading. 3 to 5 5 to 8 8 to 12 and boiling. Target at 1000 yards. Come back about 60 percent of the distance and focus / read mirage. Keep same focus and use 14 to 18 power,, so it doesn't intense the target bouncing around like a rubber ball.
Cosines method. You better be a person that do this on paper or have a calculator with the Cos button. It blows that bull crap clock method to pieces and ends up,, about 70% less moa used, compared to 1/2 and full value claimed to be used, with clock. Wind x .707 if I done it correct and hit the target in 12 MPH but not in the kill zone or center of plate at 600. Im still struggling on this one and reading a mirage half decent.
Now throw in what most forget or don't figure in with the wind speed. Wind temp. We run data but leave out wind temp in that part of correction be made to impact the target. 30 to 90 degree in temp differ just added or took away many inches at 1000 yards. What does the mirage look like and what is the temp in the bullets true path of flight,, because you done this at point A to B level line and forgot that bullet might be 100 to 400 inches above what you looked at. Boiling mirage is crazy and will bite you bad if taken for granted. Tail or head wind and I knew high or low but that boiling sucker will shift very fast and held low as I should have,, but missed by 14 inches left when not reading it right or shifted in 2 seconds.
Differ cross winds from muzzle, 200 yards to 600, is plain out kicking my butt. Tried splitting the differ and in-between, with no real success. Sure, I hit every time but looked like buck shot hit the target.
Ok, what is the best method and consistent way to figure it out. I didn't use a wind meter and flags / mirage only. Not best way I know, but really didn't want to depend on instruments and I know lots of practice is needed. That's why I have waited for windy days to try some of this.
