Description
Commercial die manufacturers have no set standards for the expander ball in their dies which means large variations happen from manufacturer to manufacturer.
We recommend removing the expander ball completely from your resizing dies. Your last step before adding powder will be to expand your necks using the appropriate expander mandrel. We recommend using a minimal amount of dry lube on the mandrel when expanding. We use a single-stage press to seat the primers and then expand the necks on the downstroke, you can the pack your “ready for powder” brass into your reloading tray – we recommend the APW Reloading trays.
The APW die body fits your normal reloading press and the interchangeable mandrels are sized to precise dimensions. The kit includes mandrels for running 0,001 or 0,002 neck tension as well as a base to keep everything in place while not in use.
The AWP Expander Mandrel will smooth out and slightly expand the case neck so the brass will be ready for consistent neck tension. We have found this is the easiest method to greatly reduce your extreme spread (ES) and standard deviation (SD) numbers.
