Reading the wind.

Trevor60, plain and simple reason for the dropped point to elevation. First you need a big set of brass balls to make a 6 minute change between shots.

Agreed in my short time shooting have never spun 6 mintues of wind and shot now ask me if i have spun 3 min the wrong way and having to correct with 6min then sadly yes LOL

Shooting irons is very different than shooting scope. Things change between when you last looked thru the spotting scope until you fire the shot and get back to the spotting scope. I have seen where I was shooting with 6 or 7 minutes left wind. I took about 15 second to get the shot off, when I got back on the scope everything looked the same. However in that 15 seconds it took to fire, the mirage when to a boil, then back to 6-7 left. The shot was right on the waterline in the dirt between the target frames.:redface:

That is one of the things I like about F class i can continuely see wind conditions through my scope and adjust or not accordingly.

Scout..up to this point i have never experiences a situation where the boil has lasted 45sec. Connaught is not the kind.

"Wind flags lie," I like that. Its a source of amazement to me to watch the wind socks at the airport indicate one wind direction, yet the snow blowing across the ground indicates another. But what's even more of a head shaker is when the windsocks at apposite end of the runway indicate opposite wind directions. Long range riflemen know that close range wind has a greater effect on bullet impact then by wind closer to the target, due to the greater amount of time the bullet is subjected to the effects of the wind. But this is only true when the wind is a consistent strength and direction between the muzzle and the target.

Obstructions can disturb the wind between the muzzle and the target. An obstruction might be a hill, vegetation or trees, structures, or just the shooter's proximity to the ground that changes the wind's effect on the bullet. If you work out your windage based on the wind at your location on a hillside, and you shoot across a valley at a target on the opposite hill, you might find that you need to put on more windage than if the bullet flew close to the ground all the way to the target, just like the snow blowing along the ground doesn't agree with the direction indicated by a windsock.
 
The problem with wind flags is that they are generally 20ft or more up a pole.You are shooting closer to the ground.
It can be 2 totally different winds.The fun starts when you are far enough back to send your bullet up to those heights momentarily before it comes back into your zone.
 
Yes wind flags do lie sometimes (just to make it interesting, at other times they work great!).

Also at times mirage can lie too, and it is even harder to figure how that can be.
