On looking at the batch of ammo that was faulty some of the cases have a soot ring appearing around the primer although the primer didnt drop out.
bigjedd,
Do you know if any of these cases with the soot ring around the primer, were fired early in your shooting session that day?
Early in the session any fouling problems should have been far less than towards the end of the 50 or so rounds fired.
I'm interested to know if primers were showing any leakage (soot) in the first 20 rounds or so.

The cases that have soot marks around the primers also have a color change at the throat of the cartridge which looks a little like annealing marks. This may have been caused by a hot chamber.????
The chamber would have to be VERY hot to ever be able to anneal the brass cartridge case.
The difference in colour "could" mean that the brass was of a different hardness on those particular cases, compared to others from the same batch.
