I have seen shifts like that ( not a full 4″ but maybe 2″ ) not allows to the right though. I tend to chalk it up to harmonics but naturally , who knows. As long as they group well.
Where is the precision .30 ammo? It is looking like the .30 is an outstanding cal. for high power airguns might be fun to try some higher BC ammo in .30.
