grayfox (and Klem) I understand all of what you say. Clearly there is not enough statistical data regarding this failure to be outright proven, but note that there is not enough data to prove the otherwise or any other failure as well. All of us can only speculate and give our subjective opinions here (which to me is the point...and fun!). It goes both ways with point and counterpoint on a technical debate. As an engineer I am just working with the "data", albeit anecdotal, that's just available in the moment. And of course we should have other failure models on the table here and keep them open too.
And just to be clear on my position/current opinion, I definitely think OP was running a hot load. He was above Hornady's max load with a Hornady bullet. His casing could have easily been Hornady or Norma and still fail.
Also I agree about Lapua being too expensive to be worth it.
