Expander Mandrel Set
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 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 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 APW Expander Mandrel will smooth out and slightly expand the case neck so the brass will be ready for consistant neck tention. We have found this is the easiest method to greatly reduce your Extreme Spread (ES) and Standard Deviation (SD) numbers.
