It would appear that in India, this powder chamber in one form or another became standard, even when it wasn't required anymore when corned powder came into use.
There shouldn't be a gap really between powder and ball, so they likely had it measured pretty close so as to not create problems. (For instance, just enough powder to fill the chamber, and a tad more, so the ball sat on it, (or the wad) without unduly compressing it.

Hi Richard.
Your mealed powder analysis makes perfect sense. I have actually seen some of this powder. It's almost the consistency of cake flour. But I did not know of it's ignition requirements. Thank you very much. I learn something new on this Forum all the time. The theory for the powder chamber design becomes more clear.
Hopefully, between the gunsmith and myself, we will be able to figure out a way to safely shoot the barrel without the use of a new steel liner. Which in this case, would be expensive to make with a large taper for the breech section, but the bore being the same diameter the whole length.
Which brings up another question LOL. I wonder how they kept the breech area clean after firing? Running a cleaning patch down the bore from the muzzle end would likely loose the patch in the breech area. Would it not?
