[QUOTE="rscott5028, post: 513795, member: 24624"] It is possible to "ditch" the expander. But like Boomtube points out, it's there for a reason. And, without a method to manage the shape, concentricity, and diameter inside your neck, you may be doing more harm than good. For example, neck sizing with a bushing die and no expander is just going to act on the outside of the neck. If you don't have consistent neck wall thickness for a given case or lot, then your neck ID's will be inconsistent, non-circular, and/or eccentric. This can be overcome by turning necks which comes with it's own set of challenges. Measure your neck-id. Then, chuck the expander in a drill and polish it with 600 grit sandpaper. You don't want to remove a lot of material and cause a lot of neck tension which will also work harden your brass. You mostly want it polished a bit so that it creates less stress on the neck as it passes in and back out. ...a little bit of Redding's dry neck lube can help. If you don't measure, you may be going from bad to worse. -- richard [/QUOTE]
