What is the FPS of the discovery using C02 for .177 and .22 ? I have found the numbers for Air but not for C02.

What I'm curious about is why would anyone want to change it? I can't imagine the need to switch, Can someone explain any advantage?

You'd perhaps want to change to not have to pump. Bulk filled CO2 is cheap and can be obtained from many sources. A small 20 oz tank will provide quite a few refills and only costs $30 or so. The initial investment is less than a similar compressed air tank (generally, bt not all the time). Some folks don't have compressed air fill as readily available (dive shops).

On CO2 the .22 Discovery gets about 650 fps. in .177, I'd expect 750 or so.
