WHat the when I pumped my pocket blaster 15 times and shot it with no dart it made a huge POP and smoke came out rising up. This dosen't usally happen to my guns.

I tryed a few more time a half the time smoke comes out very weird.

yeah, it happens.

My at2k smokes every time it fires. Maybe its the copper barrel, because my brass guns don't smoke.

It's just air depressurizing at such a fast rate as to cool down the local water molecules enough condense. With a shorter barrel, you'll notice it more often. Works best if you let the pressurized air inside the tank cool down a bit first. The quasi-laminar flow you get with a barrel will make the "smoke" more... Well, smoke-like, than without the barrel. I'm not sure how long a barrel is best, but I'm sure the barrel also has a limiting effect to diffusion (limited volume, after all) and heat exchange which enhances the "smoke" effect.

But be assured that it is not, in fact, smoke, nor is it to do with the barrel material.

At least it shouldn't have anything to do with the barrel material...

Adding to what zero said, the sspb probably foggs more because there's some moisture in it somewhere. I've frequently found that after I run water through my modded xp150 it fogges quite a bit, and my 1500's fog alot more when I've recently dunked them in water for a leak check.

I thought it was compressed CO2, not water....

Well then its probably my barrel length instead of material because my copper barrel is considerably shorter than my brasses. Thanks for the clearup zero.

I don't think you're going to be getting deposition of CO2 at the pressures an SSPB can take... I mean, the most one of things could probably take is what? 120PSI? So that's about 8.16atm, at which point CO2 would first reach a liquid state at about -43ºC, according to the pressure-temperature phase diagram I have here. Considering the fluctuation of pressure and temperature, but within reasonable limits, I really doubt that's CO2. Water has a much closer condensation point, so unless it's something crazy like deposited Argon through some inane vortice formation, I'm quite sure it's just water.

Ok I don't want to even try to get what your saying there >_<

Lol Zero, I understood that, but most of the stuff was pointless. "deposited Argon". Heh. But anyways its water because its more of a room temp. compared to what you would need for CO2. Maybe if we did that in Antartica or something it would be CO2.
