I have always heard it referenced as the "Point Blank Range", and is the max distance that the shooter will not need to offset aim to hit his target, depending on target diameter.

For indirect-fire weapons it's called the "Maximum Ordinance". But I've always called it the "maximum offset" (which is probably not correct) in terms of direct fire.
