This here is my certificate that shows me that my India made French 1728 Flint Musket has an official German proof and is save to shot nearly 190 grains BP behind a 750 grain bullet!
First, you must know how this is done.
The gun is inspected and the bore size and the touchhole is measured.
(They measure the touchhole 'cause it could not be more than 1.5mm - that’s the reason I order my muskets without a touchhole drilled. If it is bigger that 1.5mm - no proof!)
They have a list of bore size and this shows the proof load of powder and lead.
Sorry, but this is all in German:

Then the gun barrel is measured a second time but this time outside measurements are taken - muzzle - the middle section and the breech.
Then the gun is fixed in a device and loaded with the proof load. When everyone is behind the closed door, the gun is fired.
Then they measure the gun again. If one of those measurements does not match the before taken ones, the gun failed.
If they match, they will fire the gun a second time. Again measured and if match you get the above certificate plus some little stamps on the barrel.
If they do not match, the gun failed the test.
The little stamps on the barrel are as follows:
- the proof house mark (each house got a different one)
- the "Staate" this here show "Bavaria"
- the date. Here we have a code system:
"08" is the month = August. "BE" indicates the year with the following code:
A = 0
B = 1
C = 2
and so on up to 9.
So "08BE" turns out to be August 14 08.2014.
the next tells you the caliber = 17,5mm.
The last one (on the right close to the stock) reds "PN" that stands for "poudre noire" = BP.
So by looking at the stamps, you can see what kind of powder and the caliber and that the gun is officially proofed.
The certificate itself shows
- if muzzleloader
- number of barrels
- the guns serial number,
- the origin of the gun (india in my case)
- the bore size and
- the way of ignition. (flint or percussion
- ball or shot
Then it show you from left to right:
- the projectile - here it says "Ball" its weight - it says 50g (g = gramm
NOT grain!)
- the BP charge 12g (again gramm)
- and the equivalent charge 9 gramm of Triple Seven or Pyrodex or...
You can be sure, if the gun is used correctly - means within this range of powder and lead, it is safe to shoot.
You also should know that there are different proofs for ball, shot and even blank-firer.
I have reworked several Inida made flinters that came here without a touchhole doe to the above stated requirements. NON of those have ever failed such a test firing.
Hope that clears the dust a little. If you have any further questions about this, feel free to ask.
You asked if those are workhorses - YES they are. And since I have worked with many India made guns, Loyalist Arms delivered me the best quality.
Thanks for listening. :hatsoff:
