I agree scope is most likely the culprit. If you have iroin sight try them and see what happens? if she shoots good then you know for sure. Check your rings and mounts to ensure they are tight and not damaged. Have a gun shop check it over and boresight it again for you, then try 25 yards and 100 to see if you can get it ironed out. If you have to borrow a gun, don't take that out in the field as it sits not very ethical IMO.
