I was thinking about different configurations, and I wanted to know if anyone had real-world experience with the number of usable shots from a full 3.5 oz CO2, mounted vertically on a classic mag with a level 7 bolt, shooting around 285 FPS, at say 75 degrees ambient temperature.
Some standard numbers I've seen after Googling show 150-200, but always with the disclaimer that "depends on gun, velocity, temp etc".
I am looking for at least 200 usable shots. If it cannot get to that, would any other additions such as an expansion chamber or Palmer Stabilizer help with the efficiency?
