No, it looks typical for a blown chamber, to me. I have a close friend who blew the chamber out on a Charles Boswell damascus gun years ago. He claims an obstruction caused it because he was using reloads which were housed in later AA hulls, which are supposedly subject to base wad separation. However, the loads he used were way above recommended, with Unique and as mentioned, compression formed hulls. I warned him not to use that load, that it was the wrong powder and the wrong hull. He ignored me and the result was a ruined gun, but thankfully no injuries.
There was/is no ring bulge which would indicate an obstruction, and in my mind I know the cause was an improper load. It looks entirely typical for a blown damascus chamber, to me.
