Learning to shoot in the wind.

Another method might be to give the shooter the wind info, have them
fire the shot with
correction (hold-off or sight adjustment), then have the pit crew measure the correction in
the pits. You, the instructor, knows the movement required and critiques after the shot.
This way all you need is a aiming point. You can vary the wind velocity, direction, distance,
etc. without needing to modify the target. I suppose you could even do the same thing with
determining elevation corrections.

On estimating wind speed. Most people make it into something that is not. I am firmly convinced this was done years ago by good shooters to give them an edge over newbees. You estimate the speed of people, cars, objects, balls, clubs, etc. throughout your life. That's what keeps you from bouncing into each other at the mall. Look at the mirage and estimate it's speed. Take your first "gut instinct", don't change your mind or you will mess up. Look at the speed of the mirage based on how fast do you need to go to keep up. Can you stroll (2 -3 mph), fast walk (4-5 mph), jog (6-7 mph), run (8-9 mph), sprint (10-12 mph), or do you need to get in your car and chase the sucker down (12 and above). Of course in my case anything over 5 is get in my car and chase the sucker down. Then use the math of wind speed times range in hundreds divided by the constant of the round you are using. This gives you full value wind. Now decide if the wind is full or part value. Another place that many have problems. At 90 degrees, it is full; 75 degrees is .96 value; 60 degrees is .86 value; 45 degrees is .70 vlaue (NOT half); 30 degrees is .5 value; and 15 degrees is .25 value. At longer ranges you also have a verticle displacement of about .10 of the horizontal value at 1000 yards. When the wind is right to left the round climbs high and left to right goes low, (for a right hand twist, opposite for a left hand twist). A no value head wind causes the round to strike low and a no value tail wind will cause the round to strike high. As the part value wind starts taking effect the fun increases as to high and low and will drive a man to drink. Watch the mirage in multiple locations so that a wind change doesn't go unnoticed. Always evaluate each wind call and then look at the grass or leaves. This aids in computing values of wind. Watch the wind over multiple ranges to your target and find the dominant wind or if two winds cancel each other out. When the mirage goes squirrely, stop and wait, the wind is going to change it's mind and that's its warning to you. Unless you absolutely have to, don't shoot in a boil! I know everyone loves the no value boil. Bigger than Dallas that is when the wind will make up its mind to become a full value 5 mph left to right. Unless you have a steady no value wind, without a fishtail, then a boil is an ambush!
Dam Scott, I got going again. Feel free to edit what is too long of an explaination to a short question. I guess the students have me in answer man mode! Have fun guys and hold hard.
