    Commenters are getting this backwards. If there was a round in the chamber it would be the last to go off, not the first. Whereas the rest of the rounds are directly exposed to the heat, the chambered round has a thick metal barrel around it protecting it from that heat.

      i’d think it probably depends. the barrel itself is quite large and transmits heat pretty well, given that if it didn’t shit would melt.

      compared to rounds in the magazine which are more closely exposed, but through plastic, or air, which doesn’t transmit heat quite as effectively.

      i guess we should probably put a gun in an oven and see what happens hm?

        While the oven is preheating, allow me to postulate that the thermal mass of the barrel, especially in vicinity of the breech, would require far more exposure to heat to reach the temperature required for the powder to spontaneously ignite.

        This is why hot gun cook-offs occur, because the barrel has absorbed enough heat that it’s able to ignite the powder through the casing via conduction. As such, as you would expect, after containing a single explosion (i.e. firing a round), the chamber would be warm to the touch while the exterior of the barrel would remain cool. It’s not until the metal is exposed to enough heat internally that the barrel becomes too hot to touch externally.

        So that’s my logic here. If it was suddenly 500 degrees outside, I think the safest place to hide a bullet in a gun to keep it from exploding is the chamber.

          yeah, that’s a possibility, but maybe if it’s a really slow preheat, or over a long enough time period, it might be possible.

          Although you might expect the magazine to also cook off, but if you have a round chambered in the barrel, it might be an inevitability at that point so.
