In my case and the case of a Westley that came to my attention, both tubes bulged.

Too many guns are bulging in the same place for an obstruction of wadding etc to be the answer.

All the points about occasional bulges in the field are valid but in the recent cases, too much repetition is evident for it to be dismissed as sloppy cleaning or a weak tube. A lot of guns are failing where they would previously have passed. My own observations lead me to suspect steel loads are being used but I have no evidence to support this other than the reports of the number and types of failures.
