Quick questions, when the guage shows the pressure at around 1200 or so, does it take longer to go down then when its at 500. basically, as the psi drops with use does it empty faster.
When full, the gauge should indicate ~800-1000 PSI. 1200 PSI sounds like it is overfilled (or, the gauge itself is faulty).

Since the CO2 is under pressure, it is in a liquid form within the cylinder. As long as there is liquid CO2 remaining in the cylinder, the pressure gauge will still show ~800-1000 PSI.

Once there is no liquid CO2 remaining, the indicated pressure will begin to drop. It is at this time you will want to replace/refill your cylinder.
