You should get a set of bushings for the die to cover a range of neck wall thickness for different makes of brass as well as sizing the necks in steps. I determine bushing size by measuring the neck wall thickness, adding the diameter of the bullet then subtracting the desired neck tension. When sizing with a bushing it is best not to reduce the diameter of the neck by more than .005 at a time otherwise it may increase neck runout. When neck sizing I typically do not use the expander.
