What I had learned that seemed to make the most sense to me was -
"What this boils down to is that the bullet will cross the vertical sight plane (not the horizontal sight plane) closer to the muzzle (though not by a whole lot, depending on zero distance). It will be slightly low at close range because the bullet will essentially be launched horizontally instead of at a slightly upward angle and will therefore begin "falling" immediately upon exit from the barrel." - taken from the m4 thread.
It was a interesting discussion at training since I thought the general idea was kinda common sense but hard to explain without just doing it (like lobster continually asked that we just try during the lunch break).
For min of man I guess a high chest hold will work and a little movement toward the mag, especially as distance increases seems to be what needs to happen.
