FIXED, thanks Can't get Kestrel to match true Data

[bakerp30]

I jacked my speed and BC way up and it's checking out now
am having issues getting my kestrel to match my true data, I am sure this is something very simple but I have went through and went through and can not catch it, I've changed speed, bullet BC, bore heigh, and just can't find it to match all my dope i think I get it and 2 or 3 will match up perfect but then others are off a few tenths
6creedmoor
110 SMKs 617bc
magneto speed is -2977. When I build my dope into velocity calibration app it's says 3129fps but that's seems fast
bullet length -1.338
zero-100yds
Spuhr 4011 with a DMRii "guessing bore height at 2.25"

target True dope Kestrel reading
245yds. .4 / .50
317yds. .8 / .93
411yds. 1.6 / 1.53

Have you checked your turrets for tracking? Those differences can easily be within tracking variances.

I think my scope tracks, never ran an actual tracking test, but Its accurate when I make adjustments

Are you using factory brass or formed?

It will take 5 minutes to do a tall target test. Since you have ruled out other factors its worth putting this factor to rest or it could plague you forever.

I agree with the scope tracking test. Or, depending on your reticle design, did you verify with hold overs as to dialing? Was this done in one setting at the range? Weather conditions, like was there wind and did it change during the day. Same with temperature. Don't know if I read it, factory ammo or reloads? Just trying to pinpoint what it could be with the variances.
