Miniature guns are novelty custom, unique, and sometime downright crude! Common construction materials often include pill bottles or pens. Show us your work!

If you build the cartridge with the schrader at the base of it, there's no need to come up with an innovative design - you have ever a century of cartridge firearm mechanism development for reference
It's on my "to do" list but I'm working on something else at the moment.

This is pretty sweet. I bet this'd be awesome to piss teachers off at school. If you had a way to refill it there.

The
pump I use is very compact when folded, only slightly longer than the launcher itself - though of course I don't in any way advocate or condone its use for malicious purposes.

I don't understand, how does this work? Wouldn't pushing on the end vent the pressure out of the shrader? Thus doing nothing? How does this...?

Yes it does vent it but only behind the piston. The piston moves back and lets the air in front of the piston out the barrel. It is a barrel sealing co-axial if you want to research it.

OH!! *mind block blows up* I get it now!! I could never understand how co-axials work until now. It relieves the pressure just enough for the piston to move back and "unclog" the barrel, then pow! I am so glad I finally got it!!

Very innovative. This probably qualifies as one of the smallest spudguns in history.
My only really mini "cannon" to date was a coilgun. My brother then of course had to come up with something twice as good, and three times as efficent, but it was still damned fun.

Thanks
The smallest semi-amateur pneumatic I can think of is this device:
pop-shot micro gun - chambered in 0.177 using the Brocock micro air cartridge (now illegal in the UK thanks to your lovely government

) at about 900 psi.
I haven't seen a smaller co-axial though

I could easily have gone smaller lengthwise but I wanted some measure of power.
