Sorry to give links that break the rules here, but it's the only way to prove my point.

Lots more, but this should be enough.
Edit Note--If you google search some of the scope manufacturers, you can see that some (Leupold comes to mind) state that POI does not shift with changing a scope's power for successive shots (review their scope reference sections). This is one of those subjects that hunters and shooters disagree on sometimes although other factors (loose mounts, cheaply made scope, etc.) can also influence whether POI shifts with magnification change or not. While the links to competitors violates HNI's rules, Muley's point is still valid.
