On my 22-250 Rem, the sixth load has so little neck tension the if you de-chamber a round the bullet stays in the throat. That cartridge us a bit hotter than the 223 but you get the picture. Hard brass mixed in with soft is likely to see you getting random split necks as well. Anneal the brass every five or so (for 223, my loads probably need it every 3) firings to keep consistent neck tension.

I anneal every firing. Use quality bushing dies without a button and as I said accuracy and ES are consistent from first firing till the brass is tired. Up to 8 or 9 goes on my Ackley on average.
Pretty good indication my neck tension is consistent I would have thought.

After loading a few thousand rounds you also can also feel any differences during seating and sort from there.

I was wondering how you were getting consistency with mixed firing brass.
I agree, annealing every time should sort most issues. How often do you full length size? My cases start getting hard to chamber after a while. Also how do you know when to retire your brass if you have mixed firing batches?
