Thank you. That makes far more sense than anything the OP who has been involved with this thing for 10 years has said here or anywhere else.
With that explanation, I can see a 60% fault to T/C, and 40% to the OP for loading WELL over book maximum and basically creating a bomb that exacerbated the headspace issue to a catastrophic level.
Except Selmer's example is the opposite headspace issue the OP claims to have had...
