Backflash or Backfire Breechflash or Flare

The flash produced at the breech of a gun when the breech is opened after firing a round. This is caused by the ignition (and expln) of CO and hydrogen of combustion gases at the moment of their contact with oxygen of the air. If the temp of the gases is not sufficiently high to produce self-ignition, the back-flash may be caused by a piece of smoldering or burning resi due of proplnt or bag left in the gun barrel after firing. The presence of CO and hydrogen is explained by the...
