I agree with Roadworthy,The first thing I do when I'm having issues with the gun's shooting performance, is to re-center the scope. You gotta go back to the basics to start ruling out possible coincidences . I'm assuming you have read the (pinned) post in the Air Gun Gate regarding scope cant started by Sachmo. It's amazing how sometimes I too, get caught up in the "frustration of the moment" and have to re-visit the basics to get back on track . There can only a few reasons why you're gun is doing this -> mostly scope related.
