A few weeks ago I got to play with a 25mm chain gun as used on Bradley's and LAV's to name some mounts. Let's just say the manual gave range and windage figures that would be many times what the 30mm brief gave. As what I was reading was what the gunner trained from I would assume that it was pretty conservative, just as speed figures for Abrams are given at 45 mph which is again, somewhat in error.
