I want to do a bit of review here as I've never dealt with a squib. If I remember right, a squib is when the bullet is pushed out of the case, but doesn't clear the barrel? Usual causes are no/too little/bad powder? Often you can tell as the shot sounds different? If I'm right so far, then you'd wait a minute in case it was really a hang fire, eject the case, drop the mag, and clear the barrel with a cleaning rod? Sound right?
