Don't know how my CO2 like it, but I prefer a temp between 70 and 80 to shoot outdoors without a jacket. As I get older I enjoy the warmer temps, however when it gets into the upper 80's I tend to get a little too warm. Springers I'll sometimes coat up and go shoot when it in the upper 50's or so. Sending a few pellets down range make most any day a good one.
