so how about around 20mm steel pipe ie endcap and reducerish thing aswell as 20 bar ball valve and what ever barrel i can find as i douht a carbon fiber tent pole can hold back 200 odd psi!
either that or basically the same thing with larger bbs maybe the ones of the crank case
also any aussies ere that can sugest redily available small caliber ammo ie under 8mm ish?

The barrel only needs to support pressure for a brief period of time so it can afford to be much weaker than your chamber, for example I've used electrical conduit as a barrel with 400 psi pneumatics with no problems.

PN18 means it's rated for 18 bar, which means you're safe with 250 psi. If you're sticking with a 3mm barrel though, I'd go for a long barrel and similarly long chamber if it's 20mm
Post a new thread as soon as you've sorted out plans for your modified idea.
