Found this comment on the TargetTalk forum which may interest you:
"Glad to see I'm not the only dinosaur still shooting a C-60. I've had it since 1990, shoots far better than I ever will. CO2 has one big problem: You should not raise the barrel much more than 15 degrees above horizontal prior to a shot. If you do, liquid CO2 flows into the small chamber by the poppet valve. Pressure doesn't change, volume does. And so does point of impact. If you see a cloud of smoke (really dry ice) come out of the barrel after the shot, you have this problem. The C25 pistol solved it by mounting the cylinder vertically. A few others did the same, last gasp for CO2. Not practical for rifle. Running target shooters couldn't avoid the problem. CO2 got a bad reputation because of this.
The ancient technology has one big advantage over compressed air. Good to the last drop. When your CA gun is half full, it's empty. Ditto the scuba tank you fill it from. With CO2, you can shoot all the way down to really empty. You get the same number of shots from each fill. I get over 300 shots on a single fill.
CO2 might be a bit 'greener'. Takes less energy to compress it to 900 psi than the 2800 or so of a scuba tank, and you can use all of it. You do have to chill the air to extract the CO2, so it may cancel. As long as you get the gas directly from the atmosphere instead of making it by burning trees..."
