I'll start sorting 45ACP brass when I run out of things to do.
My culling process starts when I load the case feeder. Grab a hand full of brass and give it a shake; you can hear a cracked case ring......find it and discard it.
If it doesn't fit in the shell plate or is mangled to the point it won't go in the sizing die, discard it.
If it doesn't accept a primer, discard it. Most of my culls are found at this point. I usually keep a few sized and primed cases on hand so I can just remove the offending case and replace it with a primed case and continue to load. I often find S&B, AMERC, FC, some older military and, of course, those pesky small primer cases that go in the scrap bucket.
I don't try to reclaim any of the rejects; I can pick up brass at the range much faster than I can rehabilitate offenders.
This system has been working for me for many years and many thousands of rounds. I don't load 45ACP to the ragged edge of the pressure limit, so brass thickness and case capacity are not a concern. Almost all the failures I've had have been high primers (not seating to the bottom of the primer pocket) and if I'm diligent about my post-loading QC, I'll catch them before they go in the magazine.
