I'm not aware of any special considerations give to escaping gases in shotguns. The pressures are usually in the 10,800 LUP or lower range. Far lower than the 50,000-65,000 CUP/PSI of rifles.
I remember one case head separtion of a factory Federal case in a Remington 3200 many years ago. I wasn't even aware it happed until I opened the action.
