Barrel cooling - I am trying something new

[fseaman]

Could you not just mist with water?

Based on my knowledge of metallurgy, machining and gunsmithing (amateur).

I would advise against this.

There is also the wet rag/towel idea but same.

We're talking about cooling from something like 190F to ambient, and not that rapidly either. What metallurgical concerns do you have?

Years ago, I attended a Soviet Weapons Armorer's course at Front Site in Arizona. We fired the PKM machine gun until the barrel was nearly glowing, and then the instructor removed the barrel from the gun and dunked it into a 55 gallon drum of water. This occurred many times over the course of a day and did not seem to have any negative effect on the machine gun's operation or accuracy. I think there are some situations where rapid water cooling may not be an issue.

I have been trolled so much that this kind of reply question makes me warry.

It's "designed " for that. It's a machine gun not a rifle you are trying to hit an Elk with at +500 yards.

Apples and oranges.

Yes, because soviet machine gun accuracy is world renown. It might not be possible for it to get worse, so sure.
