Could you please double check the dimensions of your cartridge ?
Here are some explanations about this cartridge.
Some people say it is rimfire and some say it is centerfire.
A) First at all this cartridge is from Felix Warnier.
Here is for example one of his trade mark.
Therefore it is made for Felix Warnier, even perhaps loaded by him.
But the case is not manufactured by him, but surely by SFM (or Cartoucherie Francaise if it is from after 1905).
B) The confusion comes from a SFM drawing (N°12911 dated from 1904)
Usually the 7 mm RF Flobert rifles (which are a lot less common than the 6 mm or 9 mm flobert rifles) have a short chamber (10.5 to 11) when they have a rifled bore and are designated to shoot the ball ctge.
Here are two examples of such chambers:
The drawing 12911 shows the two chambers of a rifle made by Warnier.
One is for the 9 mm Flobert shot ctge, the other one is given for the 7 mm Flobert ball ctge.
Most of the people think at first it is not for a 7 mm Flobert ball ctge because the chamber is too long.
They think there is a mistake on the drawing, the draughtsman writting “for the 7 mm Flobert ball ctge” instead of writting “for the XXX ball ctge”
And they think this chamber is for the ctge shown by Paul.
It is not good for two reasons :
- there is no mistake in this drawing, it is really a chamber for the 7 mm Flobert ball ctge.
Not only the dimensions are ok for this ctge (as you will see by the calculations here under)
But also we must take into account there is another kind of chamber for the 7 mm Flobert ball or shot ctge as we can see on the following drawing:
- This chamber is not good for the ctge shown by Paul, the dimensions been too small (calculations here under)
As we see the 7 flobert ctge fits perfectly in the FW chamber of the drawing (we have given also the 7 Flobert chamber shown above)
But the ctge of Paul has a base diameter too big and the chamber diameter is too small at the maximum length of the ctge.
Furthermore the bore is too small at the maximum length of the ctge.
C) I do not have this cartridge in my collection and Paul didn’t give the bullet diameter (7 or 7.5 ??) and the rim thickness.
Furthermore I don’t have anymore the SFM drawings about CF and RF ctges.
Therefore I cannot tell you what it is and if it is RF or CF.
D) My friend Leveau told me all these ctges are coming from him. He made an X-Ray when he got them.
He says they are Rim Fire.
