Lost Sheep

I think I have an idea of what mikld wants. An explanation of the interior ballistics of bottlenecked (true bottlenecked, where the body of the cartridge is significantly larger in diameter than the neck and therefore greater in volume than the tapered or slightly necked cartridges of the black powder era) cartridges that make BP (supposedly) dangerous.
Excess airspace, gas flow, erosion? Speculation and, as mikld said, "internet lore"
Fact is, we all operate our own little ballistics labs, but going too far afield (e.g. using BP in a cartridge developed AFTER smokeless came on the scene and was never intended by the ammo manufacturers for BP) CAN BE dangerous, but no one has really said exactly what the danger is. Ultra-light bullets that can outrun BP's flamefront?
Thermodynamics, fluid mechanics, physics, chemistry, interior ballistics.....
Sigh.
The original thread was triggered, as I recall, by the sketchy description of the mechanical steps of loading. The powder used was a minor flaw compared to the other defects of the ehow article, now, thankfully gone.
