So I went back to the bench and took my air rifles with me and performed the same adjustments with them. While the POA does appear to shift slightly the Leapers cross-hairs physically shift a bit. Something is loose in the scope. :-( I sent an e-mail to the company. I am hoping they will honor a warranty. The scope is about 10 months old and barely used.

Here is a quick shot of my diy bench and one of my air rifles. :-)
