There is only one way.
Use the load you're going to use most & shoot at the indicated ranges, noting discrepencies (if any) from the charts. Charts are computer models only & don't exactly match real world conditions.
I have the Nikon BDC reticule & it is pretty good out to 300yds, but after that it diverges quite a bit.
Shoting at a fixed distance & calculating back the trajectory just gives you a different view of the computer model, again, not real world.
