Scopes getting mounted too tightly could indeed be an issue. But on mine, the guy building my rifle mounted the "broken" scope two times. I am assuming that he knew what he was doing. I don't think this was the problem with mine, because they worked fine for about a year or year and a half before quitting me. I visited with one of the leupold people about my scope, and they said that they had to put in a new erector spring each time. On the early vari xIIs I just don't think they were built strong enough for turning the turrets a lot. I can't speak to any other leupold products as I haven't shot them much. The POI problem I had was another issue but they fixed it. Had one of those on a Burris as well, and Burris fixed that too.
