I thought a round cooking off mostly would only happen in full auto machine guns and extended strings of fire Which is why many machine guns work from an open bolt rather than a close bolt
A cook off happens because the chamber is so hot that it heats up the powder in the cartridge and it ignites (something like 300 degrees F). So any time that the chamber gets up to around 300 degrees F you will have the potential for a cook off, regardless of whether it's a semi-auto, pump, or a bolt action.
