Think of it this way...you want your POI to go up because you are shooting low....you adjust your turret up, your reticle actually goes down, which causes you to raise the muzzle thus raising the POI to where you want it to go. The windage works exactly the same. If you think about it and picture how the turrets are moving the reticle which makes you move the muzzle to where you want the POI to be...it makes sense. It's just opposite of what you would think happens when you move the reticle by turning the turrets.There is a bit of confusion going on here......
So....
You need to put your rifle into solid gunrest.
Aim your scope crosshair on a stationary Target".
Now dial your scope Elevation knob in the "Up" direction by a couple of turns...
See which way the the scope crosshairs change in relation to the "target"
Down..........
