Did you loosen the two screws atop the turrets at all? It's possible your rail isn't on straight. If you can, check it.

Is it possible you have a 7.62x39 scope?

On the first page of this forum is a pretty good amount of info and the PSO scope Manual is there.

I had nearly the same problem with my 4x rommy scope when I first laser bore sighted it. After figuring out the scope rail was installed off angle, I decided to shim the scope base and file where necessary to achieve close to center reticle position with the laser bore sight. THis took many tries to achieve, but it eventually panned out. The reticle is now nearly dead center in the scope sighting circle with plenty of adjustment to fix any slight bore sighting errors. For example, today I took my PSL out to finish the 100 yard sight in. It took three shot to determine where the rifle was shooting with the scope( all within 2 inches of each other at 100 yds, with a big piece of paper, just to be sure). I then was able to loosen the adjustment turrets and visually track one round at a time as I brought the scope into alignment with where the rifle was shooting(probably 4 or 5 marks for elevation and only 2 or 3 for windage). When completed, with scope set at 1 for elevation, my rounds were hitting at exactly the point of the top of the uppermost chevron, first shot , every shot in a three round string. Notably, the second round was nearly always an inch to the left( father was spotting and calling), and the third was always 2 to three inches above the first two. Time between shots was about 2 to 3 seconds apart on all of the 3 rounds strings, and time between the strings was at least a full 30 seconds, with the barrel never getting above warm(to the touch). Also notably, the Czech silver tip loves my rifle, with the first 2 of 3 rounds always going into 1 to 1.25 inch clusters, and the 3rd opening it up into a 3 inch group, and russian mids 70s surp was going into 1.5 to 2 inch clusters on the first 2 rounds and third opening it up to around 4 inches. BTW, all rounds were weighed and grouped by total cartridge weight. Meaning that all rounds that weighed 346.5 grains were grouped with other rounds around that same weight(within .2 or .3 grains). Yes , I individually weighed each round out of a full case, but the result was, that the rounds were very consistant with each other and allowed the walk of shots to center of target very precisely.
