There's been quite a bit of renewed interest in "stepped" expanding inserts for LEE Precision Powder Through Expanding Dies recently. @TinManReloading and I have been discussing some of the previously available and upcoming options - including the inserts that I have made in the past.

Primed 45 Auto brass purchased at a recent gun show and second hand cast bullets from an estate make good "budget priced" components for testing the first run of the new Powder Through Expander.
