i just bought an xtra from paintballgear.com and ordered a 9 oz. co2 tank among other things along with it. i didnt notice this at first but they sent me a 12 oz instead and didn't charge me. i thought that was pretty cool. my question is, about how long does a 12 oz last? 9 oz are supposed to last for an average of about 400 rounds. so im guessing a 12 oz would last for about 550-600 rounds.
