I have often wondered how many scopes get blamed for other problems in the rifle or shooter. Probably quite a few. I did have an interesting thing happen a year ago with Leupold customer service with one of the afore mentioned vx II 6x18s. It was having a point of impact variance with a change of power. At 200yds dead on at 6x, 1.5 inches higher at 12x, and 1.5 inches higher than that at 18x. (3" total.) I shot 2 shots for each 6x, 12x, and 18x to illustrate, and sent the target in with the scope explaining the problem. A while later it came back "fixed". I remounted it,sighted in and tested it. It did the exact same thing. I redid the target again, and sent it back in. The second time it came back the problem was indeed fixed. No POI change when switching powers. Not sure why it didn't get fixed the first time though.
