How do you determine wind at a 1000

Postby Marauder 1 » Tue Oct 01, 2013 9:30 pm

OK so I've been looking at some long range shooting video and I still can't figure out how they can figure for variations in wind across that distance.

I mean here in the desert you could have variable winds due to heat and obstructions like mountains etc. It all seems so mystical.

Shooting is part Art, and part Science... especially long range shooting.

It all boils down to experience, and making educated guesses based upon your inputs, and experience level. Even then, you don't always make first or second round hits.

Technology is your friend though, and even a basic wind meter coupled with a ballistic calculator will give you better inputs than some other solutions.

You focus your spotting scope for 750 yards and watch the mirage. If it is boiling up wind is 0-1 mph, if it is leaning at an angle of 5 degrees wind is 2-4 mph, 10 deg 5-9 degrees, logarithmically for the different angle.

Another way to tell is put streamer flags every 250 yards. 18 inch long streamers help determine wind direction and speed.

There are other factors in play such as humidity, altitude(air pressure), corealis effect, and angle to target.

This should help starting at page 36. It is a good read overall.

I understand your comment about shooting in the desert , Mark .The desert here in the South-west probably has more constantly changing "variables" than just about any place I've been in my life-time . Radical wind-shifts as temperatures change . Verbals , up-drafts , down-drafts , invisible "dust-devils", canyons , arroyos , cliffs , Mtn. ranges ; small and large , and I think I've missed a boat-load of more of the same .And lets not forget the multiple heat mirages that totally destroy depth perception and "line to target" .

0933's comment regarding experience is a very over-looked part of the whole equation in my mind . Can't make a omelette without breaking a bunch of eggs . And learning ; or re-learning ( in my case ) mid-range and long range shooting is a dificult process . Even for someone who had lots of training as a kid growing up , and Sniper Training classes in Asia . Simply put ; get the proper tech equiptment . Anemometer , range finder , balistic calculator ,and then ya kidnap "T" for a couple weeks . Problem solved .... :thumbup:

If not now ....When ?

As it was said -- experience and practice practice practice. Here is something you can print and stick in your shooters log or data book.
