So, looks like it did exactly what I thought- blew out the entire shoulder of the case.
All that "missing" brass from the neck and shoulder went somewhere... hopefully most of it followed the bullet on the way out.
But as I said above, despite it being softer brass I'd check for any damage from the chamber all the way down the bore with a borescope before thinking about chambering another round to confirm no damage or obstructions.
Normally case separations occur at the casehead when that area stretches to contact the boltface- the case shoulders are contacting that area of the chamber so the only place the brass can go is to the rear. Never seen one like this where the front of the case has been completely blown out.
I cleaned bore thoroughly and inspected it. Everything look clean. I don't have a bore scope but I believe I'm good.
