Top touchhole

[TobJohn]

Would there be a benefit to having the touch hole further forward? My rudimentary understanding is a touch hole further forward would burn the powder more completely and less energy would be wasted pushing un burnt powder down the barrel.

What calibre is that one Flint?

That is the 62-cal Tannenberg bronze hand gonne from Track of the Wolf, $195. But they don't list it anymore ... they must have lost their foundry source.

If that were indeed the case ... THs on other fire locks would be far more forward than they are, and they are not. I also don't get the part about 'less energy wasted' ...

If you burn back to front, doesn’t the powder igniting at the back, start pushing all the unburnt powder forward, so there is more recoil and a higher probability of powder remaining unburnt?

This is only really based on reading I did on the Dreyse cartridge and why they put the percussion cap at the front of the powder (behind the bullet), so I could be completely misunderstanding how this works.

Sorry moderator that this is technically out of scope, but this is what I am basing it off of:

I state 'BS' on that ... as likely the inventor of the Dreyse only wrote it that way for patent protection, LOL!

And whether the charge ignites at the back or a bit more forward, if already fired ... both conditions have unburnt powdah in the barrel, duh ...

Yeah good point, and the whole “equal and opposite reaction” part of physics lol.

See? Simple c’sink @ touch hole. My hackbutt is the same, here’s the Tannenberg hand gonne.
