Rifle Scopes Question for leupold vx-6 3-18x50

[MartinR]

Hello.
Looking for a little help with my new leupold vx6 scope.
On the left side dial for the parallax, there is both a white marking line on the dial as well as a smaller white marking point on the Scope tube it-self. See pic.
What are these 2 markings are for?
Is the small white marker the one that indicates the actual parallax setting?
There is a single screwhole, but when loosening the screw, I am still unable to turn it, as it is possible with the 2 other dials. Can the favtory- setting be chances.
What is the screwhole for?

How does the rifle scope track?

Not pertinent to your original question, but I was just curious. I don't know anything about that Leupold model, so I can't help with your question, but.....Have you tested accuracy and repeatability of the tracking?

Accuracy is mest perfect and it returns to zero with no problems.
