Carbon ring is the answer to everything...
Stress forces microscopically weaken the metal enough that the corrosion agent(s) work better/faster along the stress lines. Similar things happens with steel. Were they all shot in the same rifle? Same caliber or are there others? The brass flow while fire forming to a chamber might be enough to create this pattern. Can you estimate how old the reloads are ?It looks like some sort of a stress fracture that over time corrosion found its way into the micro cracks. $64,000 question is why? I would not have been surprised if at the web area but on the shoulder is perplexing. Old military stuff that was corrosive primers and not cleaned off?
I'm trying to find out, I'll ask him next time I see him. But I think there 20-21 years old.Just curious.. Do you have any idea how old they were?

Weak brass; here's the same story from a "major" brass manufacturer this is recent with new unfired .223 brass, I won't name the company because they made it right with me and corrected the problem on their end. I had about 1500 rounds of this stuff.I was going through some of my father in laws reloads and found this. In all my years reloading I've never seen anything like it. Sure would like to know what caused this.View attachment 284828View attachment 284829View attachment 284830
How many times fired/reloaded ? Did he anneal ? Did he use any liquid cleaner that could have gotten on the inside of the cartridges ?Yes the bottom of the bullets where all that greenish blue color and granules of power stuck to them. And it's also weird that the powder formed like a rock and is stuck in the case's.
