Put a scope on my 580 mini 14 (tapered barrel) and went to sight it in. Shooting 3 round groups, no wind, every single time I had a consistent flier to the right. This happened about a half dozen times. Can't tell you if t was happening on my first, second or third pull of the trigger. Looking for some advice on how to remedy the situation. I have a picture of one of the groups below I have a recent (within the last year) magazine article that was in Field and Stream, or American Hunter somewhere in my magazine box that tells what causes which particular flier in what direction but I can't seem to find it now that I need it. If someone else knows what article I'm talking about that would be a huge help as I can probably find it online.
