I noticed some POI shifting from session to session and in trying to narrow it down did some diagnostics. I knocked the barrel to one side on my sand bags and watched for POI shift... NONE. Then I did the same with the barrel vertically. NONE.
Next, I knocked the objective of the scope. No shift.
Last, and this was the problem, I knocked the windage turret adjuster (locking ring and knob type on a Centerpoint 4-16x40) and it shifted my POI by about 1.5MOA.
I assume this is not normal. Correct?
