[QUOTE="woods, post: 428259, member: 6042"] I'm sure Mike will be along directly and give us his answer, but IMO it would be a good idea to make the ID of the neck consistant. If you have variances in neck thickness then the ID of the neck would reflect those inconsistancies. I did a test sizing with 3 methods: Lee Collet, FL die with expander and Redding bushing die. The necks on the cases sized with the bushing die were outside neck turned, a complete turn, not a skim. Then I gauged each set of 5 cases with pin gauges to .001". The pin gauges also give a little further information in that you can estimate ID smaller than .001" by how tight or loose the pin gauges go in. The Lee Collet had no variation, the expander ball cases varied but very very little (maybe .0005" or so) but the bushing die case (sans expander) varied by as much as a little more than .001". So IMO it is difficult to get a 100% consistancy from an outside neck turn and that is reflected in the variance on the neck ID when sizing the OD to a set dimension with a bushing. [/QUOTE]
