When I brought my CO2 tank home after filling last month, I thought I had a
problem as the pressure reading was barely over 500 psi (i.e. nearly
empty). However, when it warmed up to room temperature a few hours later
the reading was 800-900 as usual.
The tank they filled it from was outside, so it was undoubtedly quite cold
(a layer of ice covered it until it warmed up.) This is a 2.5 lb cylinder,
so perhaps it's more dramatic with smaller ones, but temperature can easily
make that much difference if you're dealing with winter temperatures.
