Bigger tank and higher fill pressure should get at least 30-40 shots. Pretty good numbers.

With the 350cc tank I think just extrapolating the numbers from above, you could easily get 30-35 shots

The 3000psi fill in the shot string above is only 207bar. I could be wrong, but I think I read somewhere that the 350cc bottle has a max fill rating of 4500psi or 310bar. 

Filling to a conservative 260bar and shooting down to 160bar at 3.4bar per shot is ~30 shots.
