I was about a 10th of a thou. Really excellent Taiwanese head on my mill.
That is very good. So the 0.0007" is mostly in the chuck itself, but that's still excellent for a drill chuck.

.00125, good enough for a tail stock chuck
Sorry I was unclear. I was asking in regards to the chuck runout that David posted above.
