Ammo ID help and some Vintage stuff

Must be the day for it ... anyway, as I was fossicking around my ammo cabinet I found some older stuff that I had forgotten about.
Here's some mkVI and mk VII ammo from a looong time ago. I have quite a few packets of them and no real idea where I got them from !

and a big un that a friend wants indentified that I am not sure about. Might be from one of the WW1 mauser anti tank rifles or even a Boyes?? I assume the 18 is for 1918 so probably the mauser would be my guess. a .303 Br to compare it to.

Yes, it certainly looks like a cartridge for the Mauser T13.
To be quite sure, check these basic dimensions:
Rim diameter 23.0 mm
Base diameter 21.0 mm
Neck diameter (mouth) 14.85 mm
Case length 92.0 mm
OAL (max.) 133.4 mm

Base markings (clockwise)
4 = April
18 = 1918
T67 = Tank rifle cartridge with 67% copper alloy
P = Polte Armaturen und Maschinenfabrik, Magdeburg

One of the very few types of Mauser I have never fired!

Your CAC .303 ammo is Cordite-loaded, Australian manufacture 1910 stuff: Colonial Ammunition Company.

The Mark VI Ball loading had the 215-grain RN flatbase bullet at 2060 ft/sec MV; the Mark VII had the later pointed flatbase composite 174-grain bullet at 2440 ft/sec MV. The Mark VII became the standard in 1910, although some Mark VI continued to be made for the military in some places. Canada, for example, started making the Mark VII in 1911 but still was turning out Mark VI in 1912 simply because there wasn't a single rifle in the Canadian Army that was sighted for the new loading!

You hav a bit of a treasure there, friend. You have NO idea how hard it is to find pre-War One Colonial rounds in this country!

Thanks guys. I might do a bit of a stocktake of them as there are quite a few loose rounds too. There is also a box of 1927 MkVII stuff as well. Still can't remember where I got it from but no matter, it's there ! One thing I am sure of is it is never going to be fired by me.

Just to add, both the CAC and A^F packets and rounds are Australian.

I have dug out some Mk8 Z ... I would guess that this is machine gun ammo ??
