Another one bites the dust.

[BWE Firearms]

This is what happens when you do not pay attention when loading and shooting subsonic loads. If you don't see it hit take the time to run a cleaning rod down the bore to make sure you didn't stick a bullet in the bore. You can push out one bullet with a cleaning rod. Two bullets you can usually get out with some work. Three or more just replace the barrel. It does make for a neat display.
