Design
It is essentially a necked version of the 9 mm Flobert Bosquette, with the neck serving as the reservoir for the lead shot. The most common loads consist of one-quarter of an ounce, allowing for the loading of approximately 110 #8 shots or 55 #6 shots. There are versions in which the metal neck is replaced by a paper or plastic reservoir; these are available in various lengths—much like other shotgun cartridges—with the 35 mm size (approximately 1 3/8 inches) being the most common.[3][4][5]
Its use is widespread throughout Europe, where it is employed for indoor target shooting, small-game hunting, and pest control. Historically, it has been marketed by various companies, most notably Eley, Umarex, Sellier & Bellot, RWS, and Fiocchi. In tests conducted using a 27-inch barrel loaded with No. 7 shot (containing approximately 90 pellets), a dispersion of 3 inches was observed when firing from a distance of 18 feet; the model used was a Falco 9mm rimfire.[1][3][6][7]
