Torador Barrel Investigation - Part II

kahnjar1 · 18th October 2015, 06:54 PM

Hi Rick,
Well I have to admit I am surprised! The thing which interests me is that if the patched?? lead ball when loaded has to be forced past a swamped area of the barrel, what happens when it reaches the more "open" part? I would have thought that the ball would then not be a snug fit anymore, and pressure would be lost past the ball at the time of ignition of the powder.
Also when fired the pressure inside the barrel would be markedly increased on the way out, again when the ball reaches the swamped area, which I would have thought would have increased the chance of the barrel bursting at that point.
Swamped barrels would be safe if lead shot was used rather than a solid ball.

I do not for one moment doubt your findings, but it goes against the safe laws of ballistics as I know them.

I also need to comment on the barrel itself. You would be correct in thinking the barrel was forge welded round a mandrel. That is how the beautiful pattern you have there is created. This method was also used in England and European countries, and we know there are some really exquisite barrels which have come from there.
Regards Stu
