Umm... I didn't do that test, I will do it tomorrow, But, what I realise is that the magazine some times when I fill it, that sounds of the liquid gas passing through the bottle to the mag is short and others is more longerDoes it have issues not emptying the mag of bbs on one charge? On a ~20c day you should get 2 mags worth of bbs. If you're getting that not much else to do imho... I have crap load of mags (7x extended, 10+ regular), only look for 1 mag per charge and recharge when I refill between matches or carry gas on the field.
