Default 200 + yards , swirling wind question

I about drove myself nuts at the range today trying to calculate windage.

Anybody have any tricks or tips for long range (200+) shooting with swirling/ gusty winds? (I know, bring more ammo lol)

Flags might help to judge wind and direction. Also, timing your shot for the near exact wind conditions of the previous shot helps.

I use one of these, but it's only good reading the wind for the location your at:

Learning to read the environment such as trees, grass, weeds, dust, etc... is what will rally be of help and this meter is a good learning aid for that.

Flags are nice if you're at a range ... Just take the flag angle and divide by 4. That's your wind mph.

0-3 mph wind is hardly felt in your skin
3-5 mph wind moves grass and is lightly felt
5-8 mph will keep tree leaves moving
8-12 mph will make dust and move loose paper
12-15 mph causes small trees to sway
15-20 mph makes large trees sway

What I find, is out to 300 yards, the wind doesn't have much effect if it is under 10 M.P.H.

What caliber were you shooting? Some are more affected by wind than others

What I did when I was a soldier was record every round I shot and made a ballistics chart for all different conditions such as wind and humidity and distance. Nowadays they have all sorts of ballistics calculators you can buy that will give you pretty spot on corrections if those are too pricy for you I know of several phone apps that do basically the same thing. If not go the old fashioned route and make a chart that you have on you of every round fired and the hold you used or turret settings it takes a lot of patience and ammo that way though

I know 30.06 is pretty affected by wind not too much experience with a 270 other than my ar which is 6.8spc which is 270 caliber bullet and I don't use it for loooong range. If you want a round that's a flat shooter and shrugs off wind like its nothing get a 338 lm they are one of the best long distance shooters ever and even someone with hardly any experience can easily nail consistent 700 plus targets in most conditions with one
