Dave, I'm glad you got out and shot that rifle again. But from the prior adjustment you made, it looks as though the scope is fine. I have a funny feeling it had something to do with your load combo. Either the pellets, sabot or whatever. But at least its hitting good.
I know I hate it when I get a rifle or put a new scope on and don't get to shoot it for some time. It bugs me when a rifle is not sighted in.
