Team, A month ago at a local match, I had a brass failure/ rupture. It went "pushuu" in my gun and the bottom of the brass was dislodged from the body. I am 120% sure it was not due to a double charge. Looking at what was left (see the photos), it seemed that the gun fired out of battery as there was a little bulge and split on it.  Yesterday, there was another one. Not as significant as the last one. It went "pushuu" again lightly but there was no brass rupture but my face got blasted
