It measures about 7.6x26.75mm.
Does its heft suggest it contains lead shot? Jack
No sound when shaken (not stirred). Non magnetic. The brass has an old beat up appearance.
Is it light like a blank would be or heavy as though it has a projectile or lead shot in it? Jack
I can weigh it tomorrow. It is very light by touch.
For blank firing (irritants) gun or cane gun?
There is something called 7.62x26.2R Russian.
Vlad, this does not square here. The Russian 7.62x25R is a sole WC load and just recently became a subcaliber load with a 7.62x54R T-46M bullet.
Also the rim shape here implies a very old case design which most likely is from black powder days.
Yes, you are right. It was just a guess, and a bad one.
It does look like the 7.5x26R Sarbacane Shot (FR63) although maybe it has a much thicker rim (based on the image) - I need case dimensions to be sure.
That case is known in conventional cf but I have not seen it in conventional CF without a hs. It is known without hs in Gevelot IP & Gaupillat battery cup. I am only aware of French production.
The total weight is 6.00 grammes, which is 92.58 grains. I’ll get measurements when I get home from work. I am always in a wrong place.
OK, I borrowed a world standard calibrated calliper from my maintenance department and made this beautiful drawing, all in inches. This round seems to have a slight taper at the mouth.
Sorry, the number on the left got cut off, it is 0.364.
Overall this case is c0.3-0.5mm larger than the 7.5x26R (Base, rim and mouth diameters and rim thickness and case length) which is significant and I doubt that this would correctly chamber in a Sarbacane or Canne weapon.
What else can it be: Revolver ?, Tool cartridge ??
