Well of course, or no one would even use this forum. But even at 850psi that 1mm bore cartridge surely won't satisfy your usual biscuit tin smiley face penetration test ?
I'm guessing this is all for a miniature contraption, but isn't that sidetracking on world domination ?
Don't start making rubber band guns

Clockwork birds made of gold though...
I must admit at times I have thought of making a miniature artillery piece.

Lateral thinking, my friend - not directly useful for world domination, but potentially useful practice while creating the sort of tiny artefact the ownership of which certain individuals are willing to part with considerable sums for, something I'm becoming increasingly conscious of.

It is that clockwork birds fault then after all

I would love to see a nice pneumatic handgun from you
why not try to make an on-board fueling system, with a butane canister in the grip and a venturi inlet to the pump?
With a small diameter pump like that you have the possibility to reach high mixes
Just find a way to make a reliable ignition system that's not too bulky.

No I am not, I am just saying.

No, it's this mystery object that changed it all:

If all goes well you should be seeing that and much, much more

A piezo is good enough for a mini but only for 16x or so. What might do the trick is hot wire ignition, the capability of making small cartridges with say threaded bases to make the wire replaceable for every shot would be an asset, especially because it avoids the hassle of heavily insulating high voltage wires.
edit: mini gatling springer, hmm...

so he lent you a hand, right ?
Now this is getting weird
anyway how much did that cost?

LOL!
Including shipping and import duty it's going to total around $2500, plus another $100 or so spend on drills, tap/dies etc. but my consultant assures me I will have all I need.
You know, I'm probably not buying the Merkur set we had been discussing now...

Ah, Sherline mini lathe and mill? Why didn't you get the CNC setup?
I'm glad to see you got the 8 axis mill head and rotating table. Stuff thre dimensions, you'll have 9 axis and the lathe.
That setup with the CNC is my eventual goal, I just need around $6000USD. It shall be a while.
Edit: Need sarcasm tags on
Why didn't you get the CNC setup?
. It didn't really convey properly.

I deny everything... just in case!

Here you answer your own question
The beauty of Sherline equiment is that you can go step by step... from a lathe + a milling column to a lathe + a separate mill to a full CNC equipment!
And without never loosing money because you can reuse almost all the accessories... and resell the left over (like say, the wheels when you go CNC) on eBay for fair prices.
