I'd suggest reading the beginning of this thread. A case failure cannot usefully be considered a kB! A REAL kB! occurs when significant overpressure cause the GUN to blow up, bending and ripping steel. ANY gun will blow up if subjected to pressure beyond its designed tolerance. Overpressure events usually occur when one (or more) of the following is true: (1) the round is over/double charged or charged with the wrong powder. (2) the bullet is set back in the case, reducing volume and increasing pressure, (3) a round is fired through an obstructed bore, possibly a bullet left by a previous under-charged round (a squib). Overpressure has essentially nothing to do with "unsupported" chambers.
