"To me, the case appears to have been fired in an oversize chamber, or even a .222 Rem or Rem. Mag."

That kind of case fracture is not indicative of an oversized chamber, nor does there appear to be any case deformation.

A split from an oversized chamber also wouldn't look like an aerial map of the Mississippi River.

As I said, I've seen this numerous times in the past -- it's a flaw in the brass, either bad brass, an inclusion in the brass, or locked in stress that wasn't relieved during annealing.

I've never had brass split like that but about 33 years ago I opened a brand new box of WW .357 Mag ammo and found that in 5 of the rounds the bullet was upside down. Of the 45 rounds left of that box 5 rounds wouldn't fire at all. I always figured at a box of rejects some how got out of the factory by accident???

I had some Norma in 6.5 Jap do that. Headspace was ok, but chamber was oversize in diameter. I rechambered to 6.5x308. It was a rifle that dad picked up on the "Canal".
No such thing as a stupid question. What is stupid is not asking it.
