reading wind with mirage

If I am calling in MOA, I simply firgure out how much wind it takes to move my bullet 5 MOA at 1000 yds. With a high BC bullet of .600 or so at 2800 fps, it is about 9 mph. That gives me 0.5 MOA per hundred yards to start. Then I simply adjust the call for the actual wind and direction (effective wind).

The same method works for MILS, you just use a wind that moves the bullet 1 MIL at 1000 yards. The math is easier in MILS because it is in tenths of a MIL and the numbers are smaller. For the same bullet above, it would be about a 6 mph wind used as the base wind.
 
That was a typo, i got fat fingers
I was mostly joking with you but also thinking, "what does he know".
I understand that your method is a general type thing but it does seem to be from old 168SMK@2550fps type data. Or maybe from cotton flag type corrections? 2.4moa for 4mph seems more than what a 80Amax would need.

It’s what was taught to me from the days I was still wet behind the ears, but it will still get you on paper usually in the 10 ring. Besides most novice shooters underestimate the amount of correction needed. If you under correct you’ll be short, but if you overcorrect, or what they think is over correct they are usually cenetered or on the other side in the 10 ring.
My primary coaching is with Junior service rifle shooters, this gives them something to base off of.
Now i use a wind meter, read mirage , flags etc but also have experience , which is the best tool there is.
That formula is used to give new shooters a basis to get their own experience.
 
Your best bet is to get range time next to somebody that has a handle on conditions and will explain to you exactly what they are doing.

Reading wind is not hard, establishing a solid strategy to fire within the conditions on the range is a different matter. Most can't do it. THAT is what must be mastered.
 
Funny
In the months since i started this thread I've actually got better and better at shooting and very little at wind.

Today in smallbore f-class I ran 600/600 while the wind was sticking to what I dialed in then,boom, dropped five when it did something new. My comfy condition came back ... 'nother 100 ;)

Who's book is that? I enter <wind reading> at Amazon I don't see anything with that title. What does come up is a bunch of books from $15-20.

"The wind is over rated and used to blame many bad shots by the shooter."
Love that one... "bad shots" are more often because of errors in wind reading.

"You can't look five different places at the same time...."
Well, some folks can, it's knowing what - if anywhere - at which one of those places there's something useful to be seen, then acted upon... before it changes. Kent Reeve comes to mind, and Mid Tompkins, John Whidden.
 
At our last junior high power team training session, to demonstrate wind effect and correction. To understand the mirage in a subtle fishtailing wind, we had our top shooter on the mound at 600 and shot with no wind zero. The rest were asked what would be their correction one by one before each shot, then compared their call to the shot placement. It was a good case study, the wind took the shooter from 9 o'clock to 3 o'clock, he posted about 2 inch vertical, spanning slightly less than the 10 ring width, shooting with no wind correction. The condition prevailed, he could have possibly cleaned it with no wind zero on the gun, assuming he stayed on the waterline.

If a shooter were chasing the spotter and making full value corrections, and not paying attention to the max and min and wind cycle, he could be in trouble in that subtle fishtailing wind. Those ugly 8s, and occasional 7s might just show up depending on the hold and cone of fire.

When I legged out in 96, we were shooting at Camp Bullis. At 600 yards, its notorious fishtailing condition was at its best. The fast dropping wind netted a bunch of folks 7 on the right, followed by a 7 on the left. As I was studying the wind while scoring, I noticed its repeating characteristic, though it dropped off fast, it stayed in the boil long enough by timing it that I could get off a couple of shots, before it reversed. Contrary to what I heard not to shoot in the boil, my strategy was to shoot one shot in the boil. When it was my turn to shoot I stuck to my strategy, no wind zero. First shot was a 10 at 3 just outside the 10 ring. I shot the entire match with no wind zero on the gun, and posted a 198. No one was even close to it. I won the match and legged out. Talking to other shooters after the match, no one believed that I was crazy enough to shoot in the boil, after all we've told not to shoot in the boil.

BTW, never saw another condition like that and have not shot in boil since.

IMO it is the book that is most responsible for advancing my scores in F-class...hands down! Highly recommended.
 
There is nothing like trigger time. Next best is to call wind for a strong shooter. That is mind awakening!
 
Excellent training tool calling for another shooter, may be why 2 man team is getting popular!

And shooting two-to-the-mound, where you have an interval between shots while your mound-mate gets their shot off. Then you have 45 SECONDS to shoot yours, or lose points for delay! Called Fullbore.

Wow!! I guess I should move my copy from the bathroom to the gun safe. ;)
 
I heard a story about calling your own wind, it goes like this.
Bob comes up the the line slightly late and hollers over to Al- whatcha got on ? Al says I got 9
Bob spins on 9 takes a shot and says Hey Al I just hit the neighbors target!
Al replies ME TOO!!
:cool:

Lol that’s funny and can happen to the eavesdropping. I was told a true story about a team that put several minutes on their guns well before the match. When the coach made the call to dial them back partly, the neighbors thought they could see something they couldn’t. Lol

Best way to learn to read wind by mirage is go to a match with only a spotting scope. Set behind the guy that you know has a great shooting gun and thinks every string is a race to see who finishes first. After a short while you can call his 9’s (or worse) as soon as he pulls the trigger. Hard part is having the patience to wait those conditions out when you are the one pulling the trigger.

The problem with that is not knowing what he has onthe scope or where they are holding.
