Commercial die manufacturers have no set standards for the Expander ball in their dies. Large variations from manufacturing to manufacturing and even within a given manufacturing makes it necessary to properly size the inside diameter before seating. This is where our expander mandrel comes in.
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.
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 Imperial Sizing lube when using the mandrels, a little bit goes a long way. We use a single stage press to seat the primers and then expand the necks on the down stroke, then we pack the “ready for powder” brass into our APW reloading trays.
The 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.
This set only included the following 2 mandrels for use only in the APW Expander Mandrel Set
8mm 323 Cal Mandrels only
