Excellent calculator here, with a database of published BCs from just about everyone:

Just estimate your velocity, put the zero range at 1000, and set the table step to 25, you can see where the apogee is.

I just rant it for the .308 180 SMK @ 2600 fps, and it peaks at ~575 yards, at +150.8", or roughly 12 1/2 feet.
