First thing I’d suggest is try a different scope on it but, just before you do that, loosen off the Allen screws on the barrel band and you may notice ever such a slight movement in the barrel. Then of course re-tighten. S410’s are notorious for knocking the barrel slightly out of alignment with the slightest knock of the barrel. It’s happened a good few times on mine.
