A difference of .25" for sight height is not going to make much difference. If you enter both heights into your program; 2.25" and 2.5' and keep everything else the same, the difference in drop is only 1" at 500yards. I use 2.5" as a default for AR's.
If you hit the target using a 4mil hold-over on the reticle but missed when you dialled the same on the turrets then maybe the wind got you, or dare I say it, a more ordinary reason.
How big is your target?
