I may have jumped the gun (Pun Intended) on this one. I am so used to trying all the usual suspects of loose screws on the gun or scope then cleaning the barrel and as a last resort trying another scope. This time the scope started acting like the others so I hadn't even tried anything before I got excited. Just went threw everything and found all the screws tight but then before trying another scope I did the usual of cleaning the barrel first and that seems to be the case because all is good now. Back to pellet hole groups after sighting it in. Put 50 pellets threw it and everything is holding where it should be. I new that I couldn't have had that bad of luck with scopes. So far Hawke has stood up better than anything else that Ive tried.
One piece mounts work best on springers. Also, Leapers and Center Point make reasonably priced airgun rated scopes.I'm a little concerned with your statement of cleaning. An airgun really benefits from a seasoned barrel. Most, and I, recommend an initial cleaning and then don't clean again until somewhere around 10,000 rounds. When/if accuracy falls off. But once you clean it, as you did when changing scopes, the bore should be out of the inaccuracy equation. Yep, Hawke makes an excellent airgun rated scope!!!
