The simple answer is that it depends on a lot of things.  In colder weather you will get fewer shots and the faster you shoot, the fewer shots will you get.  Also, different guns (even if they are the same make and model) will get different numbers of shots.  To estimate how many shots you will get, based on normal play, plan on getting at least 300 shots from a 9oz tank, 400 from a 12oz and 600 from a 20oz.  These numbers are on the low end as we have seen nearly 500 shots from a 9oz and over a 1000 from a 20oz.
