I've moved your thread to the ammo forum. It'll get a faster response there. Also, can you take a picture of the markings on the base of the cartridge please
and thanks for the help.
it is not eassy to get a photo of the markings on the bottom.On top there is stamped : K740 43dan
Ok. In which case just list what it says on the base of the cartridge in a reply
this is the only thing I can see
Looks like a 40mm x 311mm Bofors L60 to me.....Pete.
