In my experience every Leupold with tracking or impact shift problems were cause by the scope rings too tight or misaligned and putting a lot of pressure on the rear tube. The power ring will bind up if too tight and internally the erector assembly cannot move properly or is distorted and pushed around. Remove the stress and the scope is back to normal. This is most likely why over 90% returned have no issues. I find that people that have a lot of problems with Leupold have one thing in common. The guy mounting the scope.

In over 30 years I have had a 1960's era 3x9 scope fog up and one fairly current one with a leaning reticle. Most of my current Leupold's are 6.5-20 or 8.5-25 and I dial the heck out of them and they track great. We even dropped a target model from 4 feet onto hard dirt smashing the turret cover. Did even loose zero. I like them.
