There are three types of ballistics. Internal, external, and terminal. Programs such as QuickLoad deal primarily with internal ballistics like pressure, barrel time, heat of explosion, etc. Most other ballistics programs deal with external ballistics providing time of flight, trajectory, wind drift, etc. I don't know of any computer simulations dealing with terminal ballistics. This is where things like gelatin blocks come into play.
That being said, when on the firing line you really only need to be concerned with external ballistics. To get an accurate prediction of external ballistics you really only need what programs such as PointBlank ask for...sight height, muzzle velocity, ballistic coefficient, bullet weight, etc. The type of powder used, primer, rate of twist, and a host of other things are irrelevant in determining the things that these types of programs are designed to tell you.
