Actually, having had a bullet seated will do more for uniform neck tension than re-sizing. After seating a bullet, the neck ID should be at the perfect spot--0.001" under bullet OD. Measure some and see. This has been my finding for many cartridges--the expander gets me 0.002-0.003" under, where "perfect" is 0.001" and is found by getting a custom expander ball or, as in this, previously seating a bullet.
Your only concern is old "thumb pressure on the case with bullet nose on bench" set-back test, that you should be doing all the time any way.
Sometimes you already HAVE consistency and anything you do will simply lessen the consistency you want.
