Had a practice session at Rattlesnake range in WA. Last string, the wind picked up to a max of 20mph at full value as a storm was starting to roll through. I had a Kestrel recording the cross-winds and saved the data in a excel file. I generated sight settings based on a bullet performance with 7moa drift with 10mph cross winds. The plots are sight changes for a sling shot-to-frequency of 30 sec and FClass shot-to-shot frequency of 12 seconds. The data are recorded every 2 seconds at the 1000yd firing line. ( I wish there was a Kestrel or other device that would record every second or less since it takes less than 2 seconds for the bullet to reach the target).
Wind study at Rattlesnake Range

I would be happy with a bluetooth display on my reticle
Hell I would be overjoyed if the reticle settings would be displayed so I would not need glasses to read the turrets!BoydAllen

If your rifle had a built in processor that used blue tooth to communicate with your Kestrel, and was wired to a small battery powered stepper motor that controlled your wind turret, you could have real time automatic scope adjustments, and a rather expensive excuse for any wind reading error....a real twofer.

A failure to plan is a plan for failure.
One issue is that there is potentially not one wind, but many winds.
There is a short range Benchrest shooter that uses several sensors, gathering both speed and direction, down the range. He has a program that aggregates them and displays on a PC the current POA to maintain POI.

Interesting, I was under the impression communication devices were not allowed at the bench for BR matches. Is this no longer true or did this guy find a loophole in the rules?

In some formats it is legal. In some it is not.
It is always intended two be used with wind flags. Where it is not legal, it is used to teach yourself how to read wind flags.

I was using a variation of the .243 similar to the 6SLR; and I was using the 115DTAC.

That is some very interesting data....... Thanks for sharing !.!.!
One of the data sets that I also find interesting is the DA and the amount of variance to it. It really shows how vertical dispersion would/could be affected ballistically, in a matter of a few seconds, let alone over a few minutes.

Looks like it wasn't too harsh of a day at Rattlesnake.
