Drew, here it goes for the last time on this subject, look at the pictures of the explosions you provided. None of your explosions show a pattern and most of your explosions extend for an extended length of the bore. The W. Richards in question has the explosion begin about 6" from the breech is perpendicular to bore and follows the circumference of the barrel to the soldiered joint and ends with no further apparent collateral damage to the beyond the 2" exploded area. Axial shaft is my term, so far the Brits have not adopted it. Drew what recommendations do you want? Are you asking about a 410 ga. or an 8 ga. or something in between, Whitworth steel or wrought steel, RST loads or somebodies unknown handloads, your mint Parker or a used up Crescent Arms double. Wonder why opinions might differ?
