[2019] Disappointed in this. Even after they finally added this to the creative Consumables section it can still not have unlimited uses. By default it has 15uses in creative. And when unlimited ammo settings are on it shows unlimited uses. However in game it still caps at 10uses on both occassions.

This is a bug, and it's fixed in the next major release. We couldn't get this done in time for 11.20.
