I tryed to use the search function, I tryed tank and volume, but nothing came up, and the one you found was at 16 bar, how ever I did find one for full pressure later on, and it said it was only a litre of co2 at full pressure in a 20oz tank, so either what I have found is wrong, or I really need to re think my ram size. And thanks for your help, it was quiet late when I searched it, so I probably didn't do it very well.
