Any chance you wear glasses with astigmatism correction in the lenses? I had the same issue with a similar Leupold scope AFTER I got new glasses with progressive lenses and astigmatism correction. The vertical cross hair looked tilted and I thought the scope was screwed up, but it was my glasses. A slight shift in head position looking through a different section of the lens of my glasses solved the problem. Now I'm using a Firedot reticle, so no problems now.
This. I had those issues when I wore glasses.
