Terminology and scope funtion first.
Impacting 3" right would be .8 Mil
You moved the turret left "three clicks" that would be .3 Mil, so you should have still been .5 Mil right
Now, the other factors we have to eliminate.
Is this a known rifle and load that can shoot inside 1/10 Mil?
How heavy is your tirgger?
Is your breathing and trigger control solid?
I ask this before you go through the trouble of sending the scope back to Leupold. I've had many rifles and scopes at my range that guys couldn't make shoot. Then I get behind it and the rig shoots exactly where I tell it to.
No, you don't have to tap on the turrets of these types of scoopes. You should be able to dial up 10 Mils (100 clicks) get 9.9 or 10.0 or 10.1 Mils, shoot, and dial back to zero and still have a rock solid 100 yard zero.
