The point I'm making is IT DOESN'T MATTER, how high off the ground the max ordinate is, whether its 1 ft, 10, feet or 100 feet.
What does matter is regardless of what you shoot, or how far you shoot the maxi mun ordinate will be between 1/2 and 2/3s distance from the muzzle to the target.
To determine wind correction, one needs to focus on the wind between 1/2 and 2/3s from your position to the target. That is where the bullet will be most venerable to the effects of wind.
Again, it doesn't matter what bullet, what velocity, or what range.
Take my 150 Gr LSWC with the BC of .286 at 1380 fps sighted in at 50 years. The max ordinate of that bullet will be at about 40 yards, or a tad above the 2/3s distance, but still to the point of max wind effect. (not that the wind at 50 yards is gonna throw such a bullet off enough to notice, but the principle is the same).
It would be hard to dispute the fact that the Army Marksmanship Unit has the best shooters in the world. Its their job, in cahoots with the CMP, to teach the military and civilians how to shoot.
To quote from the AMU Service Rifle Guide:
The shooter is concerned with the wind between the shooter and the target, so focus the spoting scope short of the target...Typically, the focus will be about half way between the firing line and the target. Care must be taken not to focus beyond hte target, as this will sometimes produce a "reverse reading" of the mirage.
We can argue all day about whether the max ordinate is 10 feet, 20 feet, or 1/4 MOA (as in the 357 case above), it wont change the fact that the bullet will be most effected by wind at a point 1/2 to 2/3s distance to the target. whether that distance is 40 yards in case of the pistol or 700 yardes in the case of the rifle.
And that, what I thought was the orginal point of the discussion, "at what point does one need to read the wind to make adjustments to allow him to hit the target."
