I have in my collection an aluminium 7.5mm MAS aluminium case.
It doesnt have a projectile fitted but did in the past at some stage.
Can anybody tell me what projectile would have been fitted to this case??
The case has in internal white plastic liner that is closed over the top of
the powder with a “+” in the top of the closure.
It has a shiny siver coloured primer with a bright red annulus seal.
The case shows marks consistant with being in a machine gun belt.
Any more information would be helpful :)
