Oh interesting.

Anyways as for your question, the way that ammo drain works is that it is a percentage of current, but it is rounded. The actual ammo on your ships is a value like 15/15 instead of operating actual bars. This was evident from a few times when they changed the resupply costs like on KTKM, Agano class etc. The ammo on the ship would remain what it was prepatch. Support expeditions once did not require refueling every run and multiple unresupplied sorties could be conducted similar to this (until it finally reached 0 fuel).

For example, Mutsuki class consumes 15 ammo, which doesn't round into 10% bars perfectly. So sending it on an expedition 21 requires slightly less ammo and is shown to use 60% instead of 70%.

As expedition 24 only uses 30% ammo it appears that it can not deplete to zero since it would require at least 60% to fully deplete.
