As I asked last time someone wished for overheating guns,
How long firing or how many continuous rounds would it take to overheat a gun?
At 15K feet temps?
With a cold wind blowing across the barrel at 200mph?
Just a thought....

It was at least in the back of the pilots minds during missions, I remembered this passage from To Fly and To Fight.
Almost but not quite head on, before he can fire, I put a withering burst into him. You had to be carefull to keep your bursts short. Otherwise, you could melt the inside of the gun barrels, destroy the rifling, and the shells would fly out all over the place. This burst was long enough to be chancy, but I can see the incendiaries bursting all over the front of him.
There are of course some details missing, in this encounter Col. Anderson had chased the 109 to the deck but we don't know things like how fast he's going, altitude nor exactly how long the burst of fire was. Also I don't know if he actually ever did melt the barrels, or know what it would actually take to do it. But at least it seems like it was a concern.
