i hate to say it.. but your question is perhaps a little too percise...
As there are many variables in your question...
1:- Temperature.
2:- Gun Settings.
3:- chrono speed. (or inline pressure)
4:- How fast your shooting.
5:- Paint to barrel size.
6:- not to mention the size of your pots!!
At a guess, you will get aproximately 700 shots from an 0.8 at 4500 PSI at the very least...
