Hi!
I am the author of one of the most popular Graphical Ballistics Programs available on the internet. I'm not sure what our total user base is but looking over download logs, I'd guesstimate it at over 500,000 users. Its also 100% freeware which makes it extremely popular when other packages run $30-70 that do the same thing.
Ironically, the name of my program is indeed PointBlank. Unfortunately due to the rules here of MM and at the direct request of Founder, I cant link it, but a very minor search of the internet should turn up results for it.
Your definition of "pointblank" is incorrect. Its defined to be the max range you can aim dead center without elevation corrections to hit a target of a specific size. My software has the ability to calculate this for you and show the trajectory.
For example lets say you have a kill zone of 8". Based on the type of bullet you shoot (its BC), velocity etc, your rifle has a unique trajectory. The max PointBlank range for that rifle would be one where at max height of the trajectory is 4", and the lowest point of the trajectory reaches -4". That distance would be your PointBlank range. Computing this range via my software would tell you exactly how high you would have to be at 100 yards to match the PBR. Its extremely useful.

Depends on your scope. Better scopes do not have arbitrary subtends. They are PRECISELY calculated and when used correctly it will indeed show you ranges. Its always amazing to me how little people understand about this stuff.
Look no offense to Founder or the other admins of this site, I follow the rules as they laid out. I'd love to be able to give you a link my website, the software itself (its free) or even the FAQ's I've written to describe all of this stuff... its not voodoo, magic or anything else. If you want the info a few quick searches will turn up alot of details I think you really should check into... there is more going on with scopes than you realize.
