I can't imagine that NOT causing a catastrophic 'kaboom!'
As for the rest, I think he is talking about 'bi-metal' jackets, where there is a very thin layer of copper (and not paint) over a steel bullet. I've not personally heard of this supposed barrel-clogging problem, other than the usual steel case debate and how exactly it fouls the chamber, when it comes to such ammo use. (and that indoor ranges don't allow steel-core or bi-metal rounds, too damaging to the back stops.) As far as I know, most bi-metal bullets are from companies like Wolf, Tula, Brown Bear, and the like. The AE 'black box' stuff is good, I've never heard of it being bi-metal, if that was in question. As far as the more technical details of 'steel case pros and cons,' do a search here on 'steel case ammo' and you will find pretty much everything you could ask about it. Personally, I've not had a problem shooting a ton of Wolf ammo through my rifles when it's all I've got, but I always do a good cleaning afterwards.
i will say that this has happened to me personally, but only on a 22 semi auto rifle...
the first round lodged about halfway down the barrel, the second round joined it, and the third round expanded the barrel enough to allow all rounds to exit, not to mention that they were probably fragments by that time.
