The RCBS part number for their carbide 3-die set is:
21412.
Hornady has now, officially, labelled their dies for
.327 Federal (pn 546509).
.32 H&R dies from Redding (88261), and Lee (.32 S&W Long / .32 H&R - pn 90809) work as well.
If you want powder-through-expander case charging, just find a Lee
.32 S&W Long expander die (pn 90490). I very much dislike the profile of their expanders, but most of that is due to personal preference, and the particular bullets I use.
