In other words, let's say you want to put your dot right on the center of a head shot at 25 yards, but would still like to engage at 100. If your dot is right on the nose at 25, would you assume that you need to hold your dot on the chin at 100?

Or do I have this all wrong? (Sorry I'm having trouble wrapping my mind around this).

EDITED TO ADD: I looked back at some of the trajectory charts and it does not seem to work that way for a 25 yard zero, at least not without some other additional holdover or something. The IBZ chart for a 50 yard zero seems to indicate that you can do this.
No you want your zero to cover a wide range of distances you could find yourself in without having to remember to hold over or under. The 50 200 yard zero is about the best as it puts your bullet with in 2.5 inches of your pont of aim from 0 to 250 yards. With a 25 yard zero you will be 4 to 6 inches high at 100 yards if you needed to make a head shot you would miss. This is what causes most new shooters to do poorly at three gun in their first few matches with the rifle. They simply don't know where their rifle hits because they don't understand trajectory.
