I am thinking the scope is to blame. I looked it over and the screws to the rings are stripped.
I am thinking that it may not be the scope or the rifle but the questionable way the scope is being held to the action. If the screws to the rings are, in fact, stripped
, this problem would be way up on the list of possible candidates for the rifle's lack of and/or inconsistent accuracy. I wouldn't change anything until I was assured that the scope has been snuggly and properly affixed to the rifle.
