today is the first time to refill my gun bottle by myself (yesterday the diving shop helped me).
i use filler connect between gun bottle and diving bottle. then turned the swtich on diving bottle and wait. after the meter shows 2800psi i turned the switch off on the diving bottle then turn the bleed screw to releasing air in the filler pipe when gun bottle still connected to other side. but anyhow. when i releasing air in the filler. a lots air come out. this really suprised me. so i think maybe by doing this also released all air that i just filled in the gun bottle too. make the gun bottle empty again.
could it happen like this?
