fire extuinguisher cannon

[tatertime]

what size fire extuinguisher and what type would be decent for a cannon? or at least i feel like a fire extuinguisher would work well. also what valve to use?

im fairly new to this, im in the uk if that helps,
this is my barrel,

although i will cut it down to a more practical length.

i realise now that im replying to a basically two year old post but any help is appreciated

If you’re experimenting with pressurized systems, please be aware they can be extremely dangerous and may be illegal depending on setup and use.
