I'm stepping from SFP into / learning dialing with MIL and FFP. I now have a question about my SFP hunting scope.

I've sighted in my SFP scope @ 100 yards (or 200) using the 15x power setting. Done. Good groups.

Now - I go to the range or field and change my power setting to 6x (or 4x or 10x). I don't touch my elevation or windage trurret. Will my POI - my accuracy - hold at 100? I'm not talking about bullet fps and trajectory ballistics - just POI at 100 at a diffent power setting. I've spent a lot of years believing I knew this. And I MAY be right that POI will hold at different power settings on my scope?? Right?? Killed a good bit of game at many yardages doing this. Always worked.

I just want to make sure I have this right.

Thank you. Much appreciated.
