it doesnt matter what the effects of it are. and when reffering to nitro, youre also talking about compressed air.
co2 is a liquid in the tank and turns into a gas as it enters the gun. but its a crappy substance and a lot of liquid gets into the gun, which then causes problems. an expansion chamber will fix this somewhat. but also, co2 is a very inconsistent substance and you will have inconsistent shots. your velocity will have big gaps. besides that, weather affects it. if its cold, the co2 will freeze and cause your gun to freeze up and shoot low. if its too hot, the co2 will get "hot" and make you have huge velocity spikes which is unsafe.
compressed air/nitrogen has none of these problems
