One thing I just thought of is if the cinder block isn't hanging from it's center of gravity, it will cant the rope. Maybe that's the problem? I use an actual plumb bob on a string. That's why carpenters use plumb bobs instead of 2x4's or whatever.
Also, IMO, setting up the rifle as close to the string as the scope will focus it on lowest power is the easiest and most accurate way of doing it. A lazer bore sight would be good if you have one but if you don't, it's fairly easy to eyeball the bore's center. It has always worked good for me.
