Ever had a catastrophic ammo failure?

Anyone ever had ammo mess up at the worst time? Tell me the story! Did it cause a big problem and how did you deal with it?

Here's the quick take: If a shot feels wrong, stop ASAP. That tiny safety check can save your bacon and your gun.

Most of my ammo failures were of my own making.
I've had case head separation on 300 win mag, blown primers for a couple reasons and squib loads along with the primer failures. As Jovy has stated if it feels wrong stop keeping the muzzle pointed in a safe direction waiting to a five count and unload.
I have a 10mm auto casing I found that was completely blown out and split down the side from the mouth to the web of case. I looked for fingers but didn't see any. I would have liked to see the handgun that fired it though.
