Ignoring the effects of repeated high stress has a long history of disaster .

The thinner those barrels, the higher the stress. Cycling metal near its yield limit puts you in the range of a possible low cycle fatigue failure.

While a discussion about ultimate strength is relavent too, if you are firing one shot, I would be more concerned with knowing if the stresses were high enough to look at a low cycle fatigue failure. That's a much lower stress.
