Well, I learned here that the head is where the headstamp is marked.Graham M wrote: ↑Mon Jan 30, 2023 6:56 pm It's really easy. Bullets are the lumps of lead that come out the front of the barrel.
Cases are the brass things that hold the powder and into which the bullet fits.
And the HEAD is the bit that the primer sits in and has the HEADSTAMP marked on it.
And finally, the whole ensemble is called a round of ammunition.
I would already agree that the bullet is the lead, the brass bit is called, variously, the cartridge or the case and the whole assembly is called the round of ammunition. The artillery call the brass the "shell case", whether the two bits are connected or not; in the case of the 25pdr, the round of ammunition is in two parts which are loaded separately, for instance - the shell, then the case containing the charge.
I wouldn't necessarily agree that it is "easy, though. Because not everyone agrees.
