John, I enjoyed your article and I think that your point about mountain air currents is certainly valid.  Shooting across canyons, especially in the high desert, can hold surprises at longer ranges (i.e. your reference to a bullet rising a foot at 400 yards).  I have experienced similar phenomena, plus the weather may be totally different way over there! 
 
Additionally, the wind usually starts rising after sunrise when the sun is out and with updrafts, mirage and stiff breezes which may be blowing in the opposite direction out where the game is, long range shots can be dicey.  I just don't take too many shots at 400 yards or more now, as I get older.
 
I tend to sight in scopes at 200 yards, verify at 300 yards periodically and leave them.  This is mostly because I have as you mentioned, forgotten to reset back to original zero.  Nowadays, I have trouble enough remebering to reset the parallax adjustment knob, let alone remember where I left windage and elevation settings.  Plius, I am not particularly interested in carrying a sniper reference notepad while hunting.  I would rather enjoy the vistas, looking for and finding game through my binoculars.

Glad you enjoyed it. Wind is certainly an interesting thing. I was just sitting in my back yard the other day, where a few years ago we planted three quaking aspens to shade the garage/shop. All three are 25-30 feet tall now, and and have just fully leafed out this spring.

The two trees on the ends are about 15 feet from each other. I was watching the breeze move their leaves (one of the nice things about quakies) and noticed that sometimes the leaves would be moving on the MIDDLE tree and not the two on the ends.

Also, sometimes the wind would be moving the lower leaves, but not the top leaves, on all three trees, and vice versa. And this was down in the bottom of a Montana valley, not up in the mountains!

Wind can be boundary layer effect (watch birds cruise on it) a few feet off water or flat ground.  Wind currents can also be laminar just like ocean currents mainly because of temperature variations between breezes and surrounding air.  I always think of air as having almost liquid properties except for low and high pressure zones which move air by differential pressure effects.

That article was just dead on the nose. As a Med. Tech. i am also interested in the analytical aspects of shooting. I have found that researching and studying the downrange zeroing and rangefinding aspects of reticles and turret systems has helped me a lot for practical application in the field--mostly for varmints. Besides that, it's interesting, IMO--maybe akin to the door that's opened up when learning to reload, compared to shooting factory ammo. It's just another pasttime that i like to have fun with.

Recently i put a 6-18x Nikon Buckmasters mil-dot scope on a 17 Fireball XP-100 handgun, and have been using it in the field for prairie dogs. Matching the wind trajectory to the mil-dot reticle calculated at the optics highest power (other than mil-cald. power), along with 1/8th IPHY turret clicks has helped temendously for 1st shot connections at long-range using the generic 25 gr. Hornady HP.
 
IMO, i think a complete understanding of the mil-ranging formula as it pertains to not only rangefinding, but also optics applications for downrange zeroing, and the proportional relationship of second focal plane reticles helps a lot for practical applications in the field.
