A quick reminder to stop and investigate if something's not right

Found this in a batch of once fired brass that a friend had purchased. I dunno how somebody could get the bolt to closed on this; it must have taken some work. There's the potential to get into real trouble here. Don't be this guy.

Looks a lot like the impression of a spent primer, don't it?

No, it's 223, so I can't really get down in there.

The left edge of the imprint is cut through in two 45-degree arcs.
 
Cases with nipples. That's a new one.

Under the right circumstances, particularly with under-spec ammo and an over-spec chamber, the inertia of the bolt in a semi-auto could do most of the work. With an AR, a couple whacks of the forward assist would seal the deal.
Choosing to shoot after having to force something into the chamber, though... generally not my preferred course of action.



(As far as I'm concerned, the forward assist on an AR is a tool for getting the extractor to snap over the rim of a hung cartridge, so it can be ejected.)
