Rifle Scopes Over thinking the F-Stop of my USO. Help needed!

[Daveworkslocal]

As the title states I have totally lost my mind trying to figure out which way to adjust my f-stop on my SN-3. When the scope is on my 308 the erek nob reads 15MOA, when I mount the scope on my Eliseo chassis I have to bottom the know out and I have to aim about 6 inches below what I'm trying to hit at 100 yards. It makes shooting groups really interesting. My question to the hide is, which way do I need to adjust the f-stop? I need to the bring the crosshairs up, but I'm shooting high, so does that mean I need to adjust the screw down or up?

Any help would be appreciated.

Ok, I need to the exact opposite of what he did. If there were a dot at 100 yards and I were to center my crosshairs on it, the POI would be six inches above that. Meaning instead of bringing the crosshairs down, I would need to bring them up.
