The other factor is that bullets with lower BC will have greater wind drift. This is even more important than drop, as drop is easy to calculate and compensate for today with laser rangefinders. I would be interested for you to run the numbers given a 10mph with your example to see what the difference in drift is. Wind is rarely an issue under 150 yds, but over that it becomes much more significant. When switching to higher BC bullets of higher weight the difference in wind drift is substantial. I don't have data on hand for two bullets of the same weight like in your example to run.

In your example, there was 8 inches difference in drop. While I agree with you that the energy is more important, 8 inches is a significant amount to me. Now stretch those numbers out to 300 yards...
