Would like to see a Myth Busters test on this. If it was hot enough to cook off the round in the chamber then wouldn't the rounds in the magazine cook off as well? Before being cycled through the action?

These are the only MythBuster test I could find in a short search...It was tested with a revolver in a oven... haven't taken the time to search for the semi-auto test.

Click on the bullets in a campfire... it was the casings that caused the impacts.. not the bullets.
