Torador Barrel Investigation - Part II

Hi Stu.
It's very unusual to say the least. There is a short 1-1 1/2" narrow section (smaller than the bore diameter) between where the ball sits in the barrel, and the loose powder in the breech. And the ball not sitting on top of the powder would seem to reduce velocity. And, could even be considered a bore obstruction!

But they seemed to believe this design, along with the long barrels, was more accurate. Which, of course, defies what you and I understand of black powder ballistics.
I think the best explanation for this bore design was posted by Forum member Richard in Part-I of my original Thread. The ancient "meal" powder versus the later "corn" powder. Apparently the old meal powder would not reliably ignite if compressed. If this is true, than that would explain the loose (non-compressed) powder in the large chamber funneling through a narrower chamber to help increase pressure/velocity to the ball make more sense.
Of course, I would not shoot the gun with this bore configuration. Especially with today's black powder, which is more powerful than even the 1880's powder. Which also means, that this barrel will require a new steel liner if I intend to shoot it.
