Much like wind drift, for any given temp or pressure change, the error will be less with the higher BC bullet. Or looked at another way, the higher BC the bullet you use and the faster you shoot it the farther you can go with simple drop charts before needing to worry about weather changes.
If using a PDA for every shot it's not that big a deal, but understanding when you actually need to use a PDA and when you don't is something people should know. That distance being farther increases the odds when speed is needed in the field.
We all know our charts can't be perfect, the things we can control we can get darned close but not perfect, so the less we can dial and still make zero the closer the POI will be, the higher the BC the less you have to dial, the closer to perfect things are. Thats why I chose high BC bullets if there is one that is suitable.
Also shooting nosler accubonds, I've had matching exit holes from 500 yards to 1350 yards, the impact velocity at 1350 was 1650 fps, so even the bonded accubond will expand some at 1650 fps.
