[quote=“Fede”]A German WWI cartridge with a cordite loading was discussed before at this forum but it won’t add anything to this thread, unless someone may think that you have a “British experimental” of some sort. TonyE surely knows better, but the only documented British 7.9 mm rounds loaded with cordite were the Q Mk I and II proof cartridges of 1939 and 1941, respectively.
Most of our opinions are based on what we know from documentation and it is very difficult to prove a negative, which means finding a document saying: “We, the DWM Berlin company, have not loaded any 7.9 mm cartridge with cordite, ever”. This doesn’t mean that this is a cartridge with a non original loading but it means there is no documentation to prove it is original. A typical situation in cartridge collecting, doesn’t it?[/quote]
Exactly, Someone with some written knowledge of the Germans trying cordite. As far as the British obtaining P131 hulls and loading them with the same bullets and crimping them the same as the Germans, very doubtful unless it was a spiked sabotaged round like the S.m.K P490 S* 16 39 headstamped rounds they produced. I have no knowledge of P131 being sabotage. 27 grains of cordite I would imagine would cause the bullet to exist I would think. If you had pistol powder it might detonate to fast and ruin the firearm but not 27 grains of cordite. I do not know fellas other than to say it is the best fake crimp job I ever saw.
