The title explains it all . . . does anyone know how long a 20oz paintball co2 tank would last a regular vortex bbmg? After some searching I got somewhere from a few seconds to several minutes. Anybody got a definitive answer please?

It depends on what sort of valve and barrel you're using, according to Neospud here:

Gas consumption: ~25-30k rounds per 5lb CO2 bottle

Well, I'm not sure about the valve but I'd be using some sort of barrel that fitted 6mm metal/plastic bbs, maybe about 24" long. If I assumed that it was similar to Neospud's one then:

5lb CO2 bottle = 80oz = 25-30k rounds

so 20oz CO2 bottle = 6-8k rounds

Is that right? hmmm. His barrel was only 12" long though so that might make a difference.

It also depends on the ROF, if his gun has a higher ROF then yours or vice versa, the figures would be off a bit.

What do you plan on doing for a 20oz CO2 tank? Do you have a paintball field near by?

Also I can't find any copper/metal tube for 6mm BB's or .177 BB's anywhere, so I use the nozzles from weed sprayers and straighten them out for 6mm BB's, pretty good fit.

Really? Man I just found my barrel at the hardware store in the tube and rod section. Mine is a 9/32 brass tube.

Yeah NZ is crappy like this, piss all Spudding materials and ridiculous prices for the stuff we can get.

Acorn Models have several types of metal tubing in various sizes. www.acornmodels.co.nz search for tube. I've emailed them about the inner diameter of their 1/4 Stainless Steel Tube ($14.21 for I don't know how long) Hopefully its about 6mm.

I might just go for a mounted two way bike pump instead of CO2. Way cheaper and apparently a few pumps will give you a quick burst so its not that bad.

Thanks for the link

Edit: Let me know if you find any good tube, I asked them for some long tube with an id of no less then 7.9mm, and i'm also looking for some tube for .177 BB's, but I could do with some 6mm too

Hey Mr Crowley would this blow gun work alright for a bbmg?

Or do you think the $10 ones form Supercheap you suggested would be better?

Not sure actually.

Do you think other hobby shops will carry similar tube? I might check out a few local ones.

check out R/C model shops, the sort that cary stuff like balsa wood and carbon fibre tubing - I get my 6mm barrels from a similar outlet, diameter is comething like 6.1mm and they're sold in 1 metre perfectly straight lengths.

Pass on that. I just heard somewhere that hobby shops stocked metal rods and tubes and looked for some online. I guess maybe others might if its something that is generic for hobbies.

Edit: Yeah, what JSR said.

Also, doesn't matter about the blow gun thing, I just found one which is basically the regular one that everyone seems to use:
