I have 6 sealed and 1 open. The tin says 100 Randzunder 4mm Lang. It also says Dynamit Nobel Akteingesellschaft Nurnberg. The seal around the outside says original-sinoxid RWS. I also have an open tin of Giulio Fiocchi-Lecco 100 Flobert m/m 6 palla conica. I also have an old box that says Fifty No. 32 metallic central fire water proof , National Revolver cartridges Williamson's patent issued Jan'y 5th 1864. The cartridges inside look like a crude bullet with a tit on it. The base is flared and appears to have the propellent in it. Can anybody help with ID. Butch

Your first two mentioned packets contain rimfire sub chamber cartridges for indoor target practice.The first one is the 4mm Long cartridge , might stop a rat in its tracks at short range , and the other is the 6mm CB loading of the Flobert rifle cartridge .
CaptNemo has accurately described the teatfire cartidges , although he omitted to say that they date from the US Civil War era and are one of the interesting transitional developments from that time . It was an attempt to circumvent the Rollin White Patent held by Smith and Wesson on the bored-through revolver cylinder , which S and W defended rigourously through the legal system and invariably won .

Muzza and Captnemo, thanks alot for the reply. I am still going through 30 large plastic tus of this stuff and I find a few gems from time to time. Butch
