I was shooting my .22 LR AR today and got something that sounded like a phfiit or phoosh instead of a bang. I could see the gas escape left and right a little bit (Glad I had safety glasses on, despite not feeling any gas on my face.) Most of the gas went down and fouled the mag.
The round clearly fired out of battery. The front half was in the chamber and remained intact. The rear, not so much.
