6.35 mm "Pistola Con Caricato
I had to Google that one, pytor.
Fugly little bruiser, isn't it.
That it is.
In the 1920s steel was still becoming steel.
It wouldn't take special alloys for this one.
The .25 doesn't look like much at first glance.
It's a straight walled cartridge, center-fire,
with a semi-rimmed head.
Here are a whole bunch of diameters for you...

That should be a fair start.
That is, and gives me cartridge dimensions. Which is fair, but
I'm after the dimensions of the actual "bullet" (the lead pellet) the
round launches. I know the pellet is at least (23.11 - 15.62 =) 7.49
mm - but that is just from the tip of the pellet to the edge of the
cartridge rim.
Warning - bad ASCII art ahead B-)
Brass Cartridge length:
0------------v = 15.62 -.51 mm

OAL Length -------^ is 23.11 mm
My question is How far left of the "v" (15.62) is the bullet seated? 1
mm? 2 mm? (Bullet over all length is 7.49 mm +????mm)
32 grains of bullet at 1100 fps - almost 100 ft.lb.
Hardly metal working.
You could do that - in plastic. 
I could. But I still want a "real" cartridge, with a lead bullet.
And I figure, "WTH - let us scale it up to take a 45 ACP." Which
is a "whole more serious" project.
Once this exercise is done, I move onto scaling up a 9mm Mauser
Broomhandle into something "serious".

That way you dont have to pay for the Saamsi book
"The socialist movement takes great pains to circulate frequently new labels for its ideally constructed state.
Each worn-out label is replaced by another which raises hopes of an ultimate solution of the insoluble basic
problem of Socialism, until it becomes obvious that nothing has been changed but the name.
The most recent slogan is "State Capitalism."[Fascism] It is not commonly realized that this covers nothing more
than what used to be called Planned Economy and State Socialism, and that State Capitalism, Planned Economy,
and State Socialism diverge only in non-essentials from the "classic" ideal of egalitarian Socialism. - Ludwig von Mises (1922)
