APW Expander Mandrel Set
PLEASE NOTE: The Lead time is 12-15 working days.
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.
We recomend 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. You dont have to use dry neck lube before expanding your necks. We use a single stage press to seat the primer and expand the neck 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 perise dimentions. The kit includes mandrels for running 0,001 or 0,002 neck tention 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 consitant neck tention. You dont have to use dry neck lube before expanding your necks. We have found this is the easiest method to greatly reduce your extreme spread (ES) and standard diviation (SD) numbers.

243 Cal (6mm)
264 Cal (6.5mm)
