The influence of preliminary period in handgonne shooting

Hi all! I want to share my theory about Internal ballistic effect named preliminary period
http://www.vikingsword.com/vb/showthread.php?t=13209

(Sorry it's a google translation !)

Thank you for sharing this
You do a superb job and your demonstration is very convincing !
You making yourself your powder, awesome!
But you can not Contol firing!
It's not embarrassing ?

It is also conceivable that in some images, shooting methods (serpentin. ..) are not represented due to... top secret.
There, it seems a theory as to the mechanisms of muskets in the table of "Nightwatching" (17th) by Rembrandt, supposedly paint upside (check)!
For the fifteenth century we find the notion of secret in the Swiss militia, who must swear not to reveal the techniques of shooting and do not use them against their own city.


Merci pour ce partage !
Tu a fais un superbe travail et ta démonstration est trés convaincante !
Tu fabriques toi même ta poudre, impressionnant !!!
Par contre l'inconvénient c'est que tu ne contôles pas la mise à feu !
Ce n'est pas gênant ?

On peu aussi envisager que dans certaines images, les méthodes de tir (serpentin...) ne sont pas représentés pour cause de... secret.
Il y a, paraît-il une théorie comme cela avec les mécanismes des arquebuses dans le tableau de "la ronde de nuit" (17e) de Rembrandt, soit disant peintent à l'envers (à vérifier) !
Pour le XVe siècle on retrouve la notion de secret chez les miliciens Suisses, qui doivent jurer de ne pas révéler les techniques de tir et ne pas les utiliser contre leur propre cité.

Ps : Si quelqu'un maitrisant parfaitement l'anglais pouvait traduire...

My English is too bad. That is why i have made mistake. I have written "pre-corned powder" but it would be better to call not granulated powder as Serpentine powder (I mean dry mix). Sorry i don't know all English terminology

Thank you for comment.
I am sure that mechanisms of muskets was not secret in XVII century Serpentines was not a secret in XV century too

It is not too hard :-) I can find all ingredients in a chemistry shop. And I can made my own coal. I didn't use electric mill but I use a hand pounder. I make about 10g in a 8 minutes

I understood like that!
Because my english is bad too !

yes of course! But all, perhaps did not even efficacity and robustness. no ?

Citation :

Im not sure. Yes serpentine was not a secret
There were few types of serpentine (macthlock...), and techniques of shooting. From the simplest to the most complicated ...
The longest to the fastest...


Also, Why write in Swiss ordonnance "must swear not to reveal the techniques of shooting and do not use them against their own city" ?

From the simplest to the most complicated

What types of "most complicated" do you mean?

We don'k know what is the secret. May be it is a way of loading or somthing else. We never will know it.

Citation :

I think:
Serpentine lock or not.
Serpentine lock without spring or spring (snapping matchlocks ?).
Serpentine lock with spring inside or outside the stock.
Serpentine lock, passing through the stock or not
Trigger with a button or lever.
....

yes, just speculation. This suggests that, there is a "whiff of secrecy" around this type of weapon.

I must try one day!
Have you ever tried the wet method (granulated powder)?

Citation :

I can made my own coal

you use the willow charcoal ?

It is common mith but there are no historical sources for button locks fot XV century

Yes, I have

Usually I use birch charcoal

this confirms your theory!

Siège, italie XVe

1 = mise à feu / firing EDIT ignition moment
2= visée / aim for

1 - probably ignition moment
2 - is the preliminary period, I think. we can see flame on the touch hole before handgonne shoot.
Best wishes, Alexander.
