On the DayZ wiki, each weapon has a stat called "zeroing." Some weapons say yes or no, but the AKM says, "Up to 800m." I have gathered that is has something to do with accuracy and I can use Page Up/Down to adjust it, but what exactly am I adjusting and how do I do it effectively?

It is very helpful to watch somebody do it correctly, as well as having the formulas available to you. You can also see him to take the shot to prove that these calculations and mil-dot estimation actually work in game.
