Aside from running out of elevation on your scope or for trying to keep within the elevation of your reticle, why do you care how much drop it is at 1000?
I'm shooting 140VLD's out of my 260 Remington at 2731fps. It's not a hot load by any means. If I upped the velocity to 2900 it would only be a 1.3mil difference between the two.
Where I do care is because @ 2731 it stays supersonic to 1375M and @ 2900 it stays supersonic to 1475M. 100 more meters of potentially predictable flight.
With 100MOA elevation on the scope and 20 MOA Rail I am good to roughly 1850M.
The 140vld has enough kinetic energy to harvest elk to roughly 625M @ 2731fps and @2900 it has enough kinetic energy at 750M. At 625M there is only a 0.6mil or 2.1MOA difference. Keep in mind a lighter bullet will have a shorter effective range (for a 130VLD it is approximately 550M)
I guess it depends on what you are looking to do.
