That type of Flobert, according to Frank de Haas' single shot book, is the strongest version and can handle the 9mm shot ctg. in its original loadings just fine, also the round ball load for that ctg. Trouble is that these little shotshells, while still made in Europe, can be hard to find this side of the pond. And I'm not sure whether de Haas is referring to the "real originals" (blackpowder) or the ones that were still around in his time loaded with smokeless. The current Fiocchi shells are smokeless, of course--I have an Italian friend who has a modern Bernardelli "garden gun" for this cartridge that he uses on pests and rabbits on his hobby farm. It's an autoloader!
