No-Go On A Hot AR-15: Does It Go Out Of Head Space Because Of Heat?

I understand what Tim is doing here. While this isn’t the typical use of Go / No-Go gauges I’ve seen, he’s trying to get a hot rifle and use the No-Go gauge to see if the expansion of the chamber from heat is enough to give too much tolerance for proper head space.
Here are two other videos I have watched before on head space check with gauges.

That’s silly. It can very easily be calculated. Expansion coefficient of steel usually given as .0000076. Multiply times degrees and the length from lug faces to gage line in the chamber.

But if you look carefully, he’s doing this to answer an issue brought up by someone else, not because he thinks this is going to happen.

I would Suspect (because I don’t Abuse Guns, as a general thing) that Most Rifles are Past their Cook-Off Temperature before this would become Important.
On the Other Hand, is there a Market for a Watercooled Barrel for the AR ?
Simple Boil-Off, or with a Backpack-Mounted Radiator and Battery-Powered Water Pump?
Hey, after the Pistol Bayonet, My guess is the Gear Queers will Buy Anything….
