I sort by headstone as well.
WCC, Aguila, S&B get separated into one group.
Ammoload, IMT, other stepped brass, and CCI Aluminum get separated into another.
The first group gets swaged and then added to the 2nd group, then loaded, every round is case gauged, then used for lost brass matches.
The rest get loaded for practice ammo. Bulk loaded, not case gauged, shot, cleaned, and shot again.
The only ones I don't keep are the Berdan primed cases or steel.
