[QUOTE="woods, post: 271817, member: 6042"] What you are seeing is springback. When the expander goes through at .201" the brass springs back the .003" to .198" (that does seem like a lot). Springback will lessen as your brass neck work hardens. The amount of springback will lessen with additional firings. Are these new cases or once fired? The other options are to go to a Lee Collet Neck Sizer which presses the fired neck inward and so springback will spring the brass back out and give you less bullet grip. Perhaps too little. Or you can get a bushing die and several bushings to size your neck to the grip you want. However, IMO, the bushing dies work best when you do not use the expander supplied with it and you neck turn your brass so any inconsistant neck thicknesses are outside neck turned off. That way when you size the outside of the neck with the bushing the inconsistant neck thickness variations are not just pushed to the inside. [/QUOTE]
