Photo of the day: This is what happens when you shoot 300 BLK in a 5.56 rifle

300 aac blackout 5.56 rifle

This shooter was lucky. If that hadn’t been a bull barrel that thing would have split apart like a banana. Apparently the mag blew out and the firearm didn’t go unpunished.

I have to assume the cartridge chambered by driving the bullet deep into the case. That would certainly be possible with sub-sonic loads, which leave a lot of case space unused. That would also help prevent an even more catastrophic failure.

Still, pretty cool to see the bullet all stretched out like that.
