Neck turning with handheld drill

So fl resize, run through expander die, uniform case necks, then run through neck die?

You shouldn't have to do the last step. If you run through an expander it should leave you .001" - .002" neck tension. That should allow your brass to fit perfectly over the mandrel. Assuming you're using a bolt gun (not sure who the hell would turn necks for a gas gun) that neck tension you have left over should be perfect.
