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 Impreial 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 tention as well as a base to keep everything in place while not in use.
The complete expander mandrel set includes:
243 Cal (6mm)
264 Cal (6.5mm)
284 Cal (7mm)
30 Cal (308)
