Generally, height adjustment resides on the top, and windage (left, right) reside on the side.

How are you planning to zero it? You could get a head start by utilizing a process called bore sighting. You can purchase a relatively in-expensive little device that helps you with this. Google the above description.

Concur on boresghting. A simple <$50 laser boresighter works great. Measure the scope centerline above the bore. Using various free ballistics programs, enter in the cartridge of interest, scope height, and desired starting range. Say, somewhere between 200-300 yards.

Have the program create a graph or table, and you will see the first crossing of the bullet path at a near range, around 20-50 yards depending on bullet velocity, going above the sight line, and then drop back to the desired range.

Simply put a reflective target like white paper or a laser target at the close range, and bring the laser spot to center up/down, left/right. You will be on the paper at the far range when you actually shoot.
