The Flobert cartridge was developed in the mid-1800's after the inventor of the breech action
firearm, a Belgian gentleman by the name of Flobert.
It was nnown as "
The Garden Shotgun" and made by many manufacturers in the early to mid
1900's for short-range shooting of small rodents.
Winchester introduced their version, the "Winchester Model 36 Shotgun" in 1920 and only made
20,306 guns; the firearm was discontinued in 1927  and stopped production of the cartridge
some time shortly after 1927.
Again, there are many different 9mm rim-fire shotguns in the U.S. and all  should be able to use
these cartridges, but as with any firearm it is up to the  owner to make sure the firearm is in good
working order before using it.
These cartridges are 1.439" or 36.56mm long, the rim is .406" or 10.33mm in diameter, the case
base diameter above the rim is .342" or 8.7mm in diameter, and the top of the case is .326" or
8.3mm in diameter.
