If there is a change in POI between powers you will see the crosshairs move.
I've seen this quite often with Tasco scopes and some Bushnell.
Not as commen today as it once was.

Not surprising, the tolerances on equipment are tighter today than years ago. This is something I've heard of, but never looked for, as I assumed that all scopes would to a small degree, so I just made it habit to treat them as if they did. More accuracy possible on highest power on my end as well.
I think the mid priced scopes today are easily a match for the highest priced optics of 30 years ago.
