The 4mm Randz Long, Randz Lang, Flobert Long Case or Flobert Largo, is a rimfire cartridge developed by RWS based on the 4 mm Flobert Short cartridge.[2]
The Randz Long cartridge uses a 7.7-grain spherical BB bullet, the same one used in the 4mm Flobert Short. It is not exactly 4mm caliber, it is 4.5mm caliber. It has the same dimensions as the Randz Court, except for the case length, and logically, the overall length. It produces more velocity than the Randz Court, and having the same bullet, it produces more impact energy.[1][2]
It is only produced in Europe and among the gun models that use the 4mm Flobert cartridge (in its short and long versions) are the |Alfa series revolvers produced by AlfaProj (Models 420, 440/441 and 461) and the Safari Sport rifle-revolver produced by LATEK[1][3][4]
