I no longer use the cartridges any more since I’ve gotten a kegerator but I have always needed 3 cartridges to finish the keg. 2 was close and only a little of the third had to be used but I could never keep it to just 2 cartridges.
Thank you for the ideas, as the 2.5 gets used first time this weekend will use the 5 lb. I have and
pick up needed paint bag tank and fitting.
Cheers, Marc
