Umarex USA RWS Floberts Rimfire 22 Caliber Conical Bullet Caps were by definition, a cartridge wherein the priming and propellant charges were one and the same. More recently, rimfire cartridges, small shot cartridges and Flobert cartridges supporting a round-nose bullet were developed to contain a small additional amount of powder as a supplementary propellant charge, thus enabling a more effective cartridge to be produced.
These are the cartridges in use today. In 6mm caliber with pointed or round-nose bullets. Primarily intended for pest control. Has small ignition charge and maintains accurate flight path. To be mainly fired from smooth barreled guns.
