Yes, I did have that happen.
It was with a cheaper Bushnell 3x9.
It is mounted on one of my 22 magnums.
After figuring out what was happening, it
dialed in satisfactorily.
I found the clearest/sharpest power setting, around 6 or 7x, and
left it there. I do not like to turn the power ring, even on my Leupolds
If I need to adjust this Bushnell up or down, I will probably
forget and go through this again.
