Range Report Scope Dialup Correction

[muleman]

Need Expert Advice!
Hope this belongs here?
I checked my true dial up at 100 yds, measured with a steel tape for Accuracy. When I dialed my Nightforce up 30 MOA it truly move 32.25" with the gun locked in a vice for absolutely no movement. I repeated this 3 times & everytime I moved from 0 to 30 MOA or back to 0 it moved at 100 yds on a Steel tape 32.25".
Now if 1 MOA is 1.047" at exactly 100 yds and I take 30"X 1.047"=31.41". So shouldn't my Scope have only truly moved 31.41" instead of the 32.25"?
My question is on Ballistics Program they have a Elevation Correction Factor, Is this where you make the correction if your scope is off like this?
Would you divide the 32.25 by 31.41 which = 1.0267?
Is this what you'd substitute instead of 1 in the Elevation Correction Factor in the program?
Hope I made sense.
Thank You,
Wayne

What exactly is the ballistics program that you refer to?

colson ,
The program is SHOOTER, under the Firearm Data section they show the Elevation Correction Factor.
After some research on this it looks like I should be below 1 for a correction factor in the program, as it is moveing (32.25') more than the correct dialup(31.41).
I think I should have divided 31.41" by 32.25"= .947 Correction factor.
I've checked 4 other scopes & non of them were dead on, one was worse than this one. I know it doesn't matter much on this until you start getting past 1200-1500yds then it makes a difference on your true dialup, & that's where I'm going with this.
Any info on this topic is much appreciated, I've got lots to learn!

Sorry, I'm not familiar with that program. I do know that you need to ensure that you are at EXACTLY 100 yards when calibrating.
