Think BC and velocity...

I.E. a 300WM w/ 165 Partitions at 3k and a 223AI with 75 AMax at 3k damn near shoot on top of each other. Only difference is the amount of recoil on your end and the amount of ass on the other.

Since drop is dialable and wind is voodoo, I'd get the voodoo factor as close as I could.
