Sighting in variable scopes?

[Bowjob]

If you sight in on a lower power, then crank the power up, you are magnifying any human error that was made on the lower power. After sighting on the higher power and cranking the power down, nothing is being magnified.
As gbk mentioned, a lower power scope isn't going to change things near as much as a higher power scope, as you said.
It can be quite noticeable on higher power scopes.

awesome thanks stu for the info!

I got caught with the eye relief thing on one scope too. The rings would not allow the scope to go back any further and I figured it was good enough at 4x I would be fine. Cranked it up to 12x and had to lean in and was very uncomfortable to get a nice full scope picture. I hunted that year with a narrow field of view and promptly bought offset rings the next off season.
