SO I went to the range with a friend, I brought out a whole crate of my rifles (litraly an SKS crate).
I told him what ever he want s to fire have at it but bring your own ammo.
he bought .223 american eagle 55 grain FMJ's to run in the mini 14's
now in the first box he ran through he had a case rip in half, clean break near the top of the case (reference picture). I checked it out, checked the bore gave everything checked out ok.
i figured it was just a bad case and told him "no big deal, but if it happens again stop shooting their is a major problem"
sure as ####, not a mag later another one rips inhalf but this time the mini rams another round home. it jammed in the top half of the broken case and stops the bolt out of battery. it was very forchenant that the primer did not go off when the free floating firing pin hit it (there was a light strike) and I had to ram it out with a cleaning rod.
The gun checked out ok, and using my hand loads no further issues were encountered.
inspecting the FC brass later I found cracking on the case head seem, cracks in the same locations that the 2 other cases broke at and split necks. When I got home I checked the gun with head space gauges and it was in spec, it chambered a go but not a no-go, confirming that the ammo was the issue.
I know that there has been debates in the past about how safe this stuff is in semi automatics, but this here confirms to me that it is not safe to fire in a repeating rifle.
