Neck Turning Preparation

Q. If I buy your outside neck turner, what do I do to prepare my necks prior to turning them? Do I just neck size them?

A. The Outside Neck Turning pilots are designed to be used after using a neck sizer or a full length sizer that has an expander ball. Here is our plan: One sizes with an expander ball that is .001” smaller than bullet diameter, for example a 308 Win die would have an expander of .307”. After spring back, the case necks should be .3060” – .3065”. We make our Outside Neck Turning pilots .0020” – .0025” smaller than bullet diameter or .3055” – .3060”. That should leave a slip fit between sized cases and our pilot.
