Not criticizing, but is that picture super small for anyone else?
I think early unlock still. After staring at it, to me the flap occurred after blowout as that's where the initial separation started, and saw the most pressure as the seam continued radially chewing the brass with powder, hot gas, and fire. If the extractor was in the center of the fissure, then that makes even more sense to me.
I see the bolt opening under too much pressure, extractor is now hooked in good, and the brass is still stuck to chamber walls. Slop in bcg tail has caused lateral shift due to the case being stuck and is now exerting even more pressure on extractor area beginning to thin it faster than the rest of the case as it's trying to pull at an angle now. (Imagine if it were bubblegum because it basically is at this point)
This resulted in a weaker area relative to the rest of the case resulting in tear beginning at that very spot and resulting in a new path for fire and brimstone to spew while the bolt is still ripping the case further.
Take a spent good case and blue it. Stick it in chamber to see where exactly on the case its unsupported. I bet it's .5-1mm behind your blowout.
We CAN measure some stuffs right? 11 pages and all I see is a spent case length lol
