[QUOTE="Mikecr, post: 652158, member: 1521"] Actually, I wasn't talking about friction. A good and consistent mandrel fit is important to precision neck turning. And so are neck lengths and shoulder angles. When a neck holds a sloppy fit to the turning mandrel, the necks/shoulders can take various angles to the cutter, and the cutter can also 'peel' more or less brass during the process. This, combined with speed & feed, make turning a trial & error process, no matter how fancy or basic the equipment. I know it can be done loose, and with good results, or not. Ideally the necks fit properly via the matched turning/expander mandrels. As an example, if you expand necks with a K&M expandiron, and then turn with Sinclair's turning tools, your results will likely not be as good as necks first expanded with Sinclair's matching expander mandrel(both conditions using new cases). I think everyone who turns understands that the mandrels are matched, and for a reason. But OP is considering a departure from this intent, by using unpredictable pre-fired brass. [/QUOTE]
