I would presume it won't matter whether the cylinder is open or not and that one will get DQed.

Especially since we should 1. treat them like they're loaded at all times, 2. whatever it's being pointed at is going to be destroyed, and 3. we should always know our target even if that "target" is up in the air.

Rule 4 doesn't fit quite as nicely into the previous sentence, especially on the swap-over reload.  ;-)
