700 yards

IF I am shooting </= 1 1/2" at 100 yards that's 10 1/2" at 700
So if all shots fall 5 1/4" above or below center, no adjustment

IF I'm shooting </= 2" groups at 100 that's 14" at 700
So if all shots fall 7" above or below center, no adjustments

But if the center of the group is favoring high or low should I make a correction?

How much high or low? Could be an anomaly, scope tolerance, bc inaccuracy or conditions input.

I figure muzzle velocity extreme spread is all over this too.

If you're using Shooter and you correct your Muzzle Velocity based on your findings all its going to do is bump your speed around 25fps per .1 mil.

The outliers are what causes a rodeo, so no, they will be even further off the mark.
How many shots at each distance

I guess I’m not explaining myself correctly

It’s a hypothetical scenario
Say it’s a five shot group

Am I correct in the first two assumptions since all shots are falling into my known cone of fire?

Regardless of my group size at 700
do I just adjust my velocity figure to match the center of the group?
I’m assuming I do.
