So I'm thinking that's .003 over correcting at 300ft for MOA and so the correction factor would be 1 minus .003 which is .997, but then I read the directions and they seem to have you dividing dialed value by actual value and that is your correction factor which comes out as .952 so I think that's it but it does not look right!
JacknSD put it like this in another thread trying to help but my brain ain't gettn it so I though I best move to another thread!! Maybe I need the why you did it the way you did written out? Thanks for helping!!
"If you meant 30 MOA moved it 31.5 inches at 100 yards then it would be: .997
30*1.0471996=31.415988
31.415988/31.5= .997
So almost no correction seems to be needed. "

Friend, you either still know what you know or it makes two of us that don't know
what we know!
Here is part of the instructions: For example, if you've come to realize your .25MOA perclick scope is actually .23MOA perclick then you'd put a correction factor of 1.08695652 (.25/.23) because you actually need to adjust more
Needles to say, (The application will always multiply by the correction factor), so if we fall short the correction factor needs to be higher than 1.0 and if it falls on the high end it needs a number smaller than one. (This is more for me to understand what I'm saying.
)
See instructions portion and it makes sense.
In your case, you dialed 30 MOA and obtained 31.5/1.047198) = 30.080MOA
Then our correction factor has to be less than "one" 1.0
30/30.080 =
0.997 Now, we both know what we know!!!

Another way to look at it:
you said:
I tested an optic by turning it up 120 clicks which puts me at 30 whole numbers of some value I'm trying to determine, the optic moved 31.5 inches
31.5"/1.047 = 30.080 MOA
30.080 MOA / 120 CLICKS = 0.2506667 MOA per click... we need a correction factor
smaller than 1.0 >(0.25 MOA/ 0.2506667 MOA) =
0.997. And again
we both know what we know.

You also said: "So I'm thinking that's .003 over correcting at 300ft for MOA"
That's correct; it's over correcting 0.003" per MOA.
3 Thousands of an inch??????? At 100 yd????? NO CORRECTION NEED.
As a matter of a fact, you're good at doing that, you should come over and check
my scopes.
JacknSD is right, NO CORRECTION NEEDED!
BignGreen, what optics are those? Is it a NightForce?

It could also be that the three of us don't know garbage! Don't know what we
think we know!
