I see what your saying but lets run some numbers
My 7mm load is as follows
160 nosler accubond at 3575 fps, its a proven load, have taken deer to 1350 yards with it.
Nosler publishes the BC at .531, the first year and a half I always was shooting high till I ran some tests, found out my actual BC for this bullet is .62.
This load sighted in at 300 yards is -80.32" at 800 yardsat
At this velocity with the BC at .531 it says its -83.6" at 800, I know this is 3" high at that range at that BC setting.
So lets say I leave the BC at .531 and jack the MV up to 3637 so its -80.33 at 800 the up and down will match up for a ways, but lets say I have a 10 mph wind. wind drift with the 3637 fps .531 BC at 800 is 41", but the wind drift at 3575 fps/.62 BC is 34.7" at the same range, so holding dead on a deers shoulder at 800 yards with the BC left at .531, and the MV moved up to make zero, you've missed before you even shot. make sense?
