I would not suspect the suspention/crosshair of the scope in this case, I think it has a lense/alignment problem. I have seen MANY scopes that move point of impactwhen power is adjusted. Most areminor, maybe the width of the crosshair, but some are quite bad.For those that do not have a vise this can be hard to troubleshoot.You will see exactly what this gentleman describes if you were adjusting AO or Power while you were shooting. Those of us that sight only on the highest power would not have a problem once AO is adjusted.

Again not saying jump to any conclusions, just my best guess from info so far. But what ever the problem, good notes and observations coupled with logical/systematic approach to a fix is what it will take.

Which brings me back to shooting several groups with no adjustment of scope at all.
