I appologize for hi-jackin your thread UMF but, who has experience with some of the latest wind/pressure calculators or gadgets? I'm going to get something in the near future and want to make an educated choice. For budget I don't know yet. I'll just have to see what is recommended and go from there. I've build two 1K+ rifles and want to get supporting tec/gear.
Thanks!

Mark,
I've used most of the wind meters on the market, at one time or another. I settled on Kestrel. HOWEVER, it must be understood, and I know you do, that wind at point of fire is NOT the complete solution and actually not a lot of it. Sometimes corrections have to be made at several points in the trajectory in order to find a "final"... and that is variable. The best features of a Kestrel... say 4500-type, are temperature, humidity, pressure/density/altitude, you can even get wet bulb temperature. Again, variable over extreme range, but much less so than wind. The Kestrel has good error values, it is not too cumbersome, long battery life, can be had with red backlight for lowlight/night use. It is a pretty good tool. As with most tools, it is not the do all/end all solution, but it is certainly better than nothing. The newest version, while a bit expensive, has a ballistics calculator built in. I'll probably have one soon, I'm a sucker for hi-tech and trying to get the most out of it. Word has it, you could effectively place the Kestrel downrange and have it feed you downrange conditions via bluetooth to your smartphone. That is pretty powerful. I have not used this version, yet, so it is still just "hearsay" to me.

Very nice.
I am continuously in the process of trying to teach myself to read wind. Mostly with little luck. ILya

Of course U know these two ya?
Apparent angle from vertical: - of smoke, flags, or short light rope U keep in ur fingers / 4 = windspeed mph
- of mirage / 8 = windspeed mph
AA angle must be read at 90, ie with the wind blowing directly from h3 or h9, so turn your arm or spotting scope as necessary
K
PS: ya,ya, the Kestrel is nicer, and more precise, but U know: old/simple systems ... sustainability ... no batteries ... environment's friendly ... hahaha (just kidding). And the bluetooth range of the Kestrel is just around 30 feet. The mirage, flags smoke etc if lucky U can read at 600yd>

Wind reading is among the first skills to go when practice/use slows. I was once very good at it, now I suck.
Lucky for me my Kestrel is quite good at reading wind at my position, then it becomes a matter of reading along the bullet path, which can be a challenge. This is a good start. And if you want to read wind well, do it allot.

HI RC!
Frankly speaking I'm still using an old japanese thing giving thermo and baro-altimetric ... MANY years of good service and still functioning! Windspeed the even older system, wet thumb etc. haha
However I've seen those Kestrel and they are really nice ... mmhh 500 $ ya?

best to watch bullet strikes, rare instance that civilian shooters need first shot stuff and just as rare for people who do need them to get them past 800 yds. If your shooting in a open desert canyon winds are more important than initial wind conditions, and sometimes nothing to read except mirage. Also if you are behind the gun strike corrections are a lot easier with todays reticles .

O yees sure! Bullet strikes is the MOST precise correction, including for not-civilians. U see the impact point (better, the spotter see it and call it) U double it FAST. However this not always feasible, moreover first shot is first shot, u know. And hunters also, they need first shot ethical kill
A+

someday I will
1) shoot at a range that has grass from the firing line to the targets
2) be flat
3) has tiny colored flags showing wind changes
4) other people that change the targets
5) ALL of the above at onetime

Dale, Do you really think there will be a range in Heaven?
Here's the closest thing to me. |

Look carefully before taking the shot and it really helps if you have shot at that location before. If you have log what sight settings you have used to make hits.
A handy method that I have used for years is: ((range in yards/100) X wind velocity)/ pre determined divisor) = wind deflection in MOA some "pre dedetermined divisors" that I use: 15 - .308 168 gr @ 2850 -- .30-06 19 - 6.5 mm 123gr H AMax @ 3000 -- 6.5-06 15 - 6.5 mm 100gr H AMax @ 3300 -- 6.5-06 12 - .224 53 VMax @ 3700 --.22-.250 These values check out and were derived using values from the Sierra Ballistics program For example -- .30-06, 168 match bullet, 2850 fps, 8 mph wind @ 3 or 9, range 585 yds -- firing solution 585/100 = 5.85, 5.85 X 8 = 46.8 46.8 / 15 = 3.12 MOA correction (3 MOA on windage) for wind directions @ 2 or 10 or not right angles multiply MOA by either .6 or .8 depending Determination of wind velocities between you and your target is a real art - mirage, wind flags, alfalfa plantings, corn stalks, leaves, waves, and ripples and above. Look across a 600 yd alfafa field and see the individual little plants bending in different directions as the wind swirls and eddies across in different directions then think about shooting in the early am before the wind acts up. |
