Not sure if you can describe it that way, but if you look into the chamber from the breech end, you can see the lines (flutes) in the chamber walls that cause the striations in the case when fired. After the round is fired, the delayed blow-back roller action then allows the gases to flow between the walls of the case and the chamber wall to assist in separating the case from the chamber wall. The extractor pulls the case from the chamber, at which time the case hits the ejector, which results in the kink in the side of the case. The empty case ends up about 33 feet (10 meters) from the shooter. This too is by design so that the "enemy" can't pinpoint your location by spotting a pile of spent brass.
