I do not have this cartridge in my possession but the owner is trying to establish what type of bullet is loaded in this French 7.70mm case. The headstamp is A.PX.1.30 D and he describes the bullet as being blackened, weighing 146gns, and having only a small diameter hole in its base. My first thought was that this is armour piercing however he says it has an open nose. He actually says he can see silver metal inside the nose. These three photographs are the best I can provide but the last image does indeed appear to show a small hole in the nose. Any thoughts please?
