Alternate Title: It happened again.
Starting to see 5.56 gun blown up by chambering a .300 Blackout about as often as someone blowing up a Glock now.
As the link says, pay attention to what you're doing!
We probably didn't hear about this from the .300 Whisper crowd because it was never really popular.
There are lots of things you can do to guard against doing this, one of them picks at an advertised advantage of .300 over 6.8 or 6.5; that it uses the same magazines as 5.56. Dedicating specific magazines to each caliber and marking them clearly mitigates caliber confusion somewhat.
