Is there a hypothesis on what exactly happened (did the gun fire by the normal mechanism of the pin striking the cartridge or somehow else (e.g. due to sparking?)?)?
But bullets are usually not ferromagnetic: they are usually made from lead (steel is (a) less dense (b) more expensive (c) harder).

You might be surprised by that "most". A recent survey of bullet casings from favela shootings found a majority to be from the military or police, and that's a target buyer for armour piercing steel.
But like I said, I wasn't in the room, I'm getting my presumption from the very careful way the article never indicates the gun was fired in any way - solely that the bullet traveled.
Ah, right, you can jacket steel in something softer. Do you have some rough estimate of how large a fraction of armor piercing bullets contain steel?
@robryk @CAnxiolytic
Nope.
@robryk @CAnxiolytic
I don't believe it fired at all. I believe, based on the wording used in the article, that the bullet moved as fast as possible toward the giant magnet - which happened to be on the other side of said person's abdomen.
Having something tear through you, even if there is no gunpowder involved, is just as deadly.
