I had a partial case head separation using a 1.8oz buffer

I think you understand statistics. Are you positive the populations of brass are identical, the loads identical, the firearms identical, the types and conditions of the shooting among all of the types of brass are identical? Only then can you say that Lapua brass is weaker than others. You know this, I am sure.

Right now you have anecdotal evidence only.

There is a reason Lapua has garnered a reputation among competitive shooters over the decades. It is considered the best quality brass being made today.

I understand safety at the field level, and the engineer is responsible for the system safety he develops or endorses.
I see trend specific to one component, and compelling explanation, combined with a large body of near-miss warning signs .

When you see a failure mode trend, and then see a difference that readily explains that failure mode - you call it out.

What I am also seeing, is what I see at the field level safety - of experts who have always said it is one thing, are the slowest to see the obvious when pointed out, and counter to their own bias.

Go look at those 4 photos, look at the fact that 3 kabooms in the last year - only with that brass, amd look at the warning tell of the ring shoulders. I'd fire an engineer who didn't call this out. It might also only fail in certain barrel at certain gas settings. Are you OK with that? I'm not.
