The rings (indicating separation), can be a little tough to spot. Sometimes you can find them by using a paper clip and dragging it through the interior of the case.
Either one of these cases would surely have cracked if fired again.
Cracks, are obvious and a learning experience, not to mention dangerous !
Luckily this case came out of the gun in 1 piece and no harm was done to the shooter or the gun.
"Discount Reloads" are not much of a discount when they create problems.
A local gun shop loaned this to me. He removed it from an autoloader.
The first case (front half) was left in the chamber by the autoloader which promptly cycled in another round.
Not all brass is created equal ! The flash hole looks off center - it is not camera angle.
