Extended shooting

This seems like the most appropriate place for this question, here goes. I see 50 rd. drums for Ruger .22's and some 1911 style .45 pistols. Is it possible to overheat a barrel or chamber using these drums causing the gun to explode?

I doubt the .22 can generate that much heat. cant say for the .45, good question though.

Why would heating steel cause an explosion?

Even in full auto guns it takes more than one hi-cap (50+rounds, 30 is standard capacity) to heat the gun to the point where a cookoff is likely. High intensity rounds like the .223 get the guns very hot, but it takes well over 100rnds fired as fast as possible before there is any risk, other than getting burned it you touch the hot parts!

The .22lr is the least likely to heat to the point of danger.

I have seen an M1 rifle fired until the handguards flamed and the barrel turned red and drooped (not my gun; it belonged to my uncle - Sam that is). But even though rounds would cook off, the barrel didn't burst and I doubt it would have.

Ok, so maybe 'explode' was the wrong term. 'Burst' might be better, hot metal being softer than cold, and focusuing on a pistol might be more to my point. A standard 1911 designed pistol with and without MIM parts and a 50 rd. drum magazine. Barrels pretty thin in those and the MIM parts have raised questions about strength in the past.
