If I zero at tailstock end, I get approx. .3mm run out at chuck?????  

Thanks in advance folks.

Roy, I'm not sure I am understanding your method of checking the run out of your stock. Are you measuring two random points 180° apart? Please clarify. Also you've said you have .3mm run out at the tail stock end. What are you doing with the stock exactly in order to then "zero" it at the tail stock end?
