Notes[]
The extra 25% ammo maximum is added depending on your weapons' modded ammo maximum (any negative percentage will be offset only by up to 25% of the weapon's own final ammo maximum value).
Mutation Efficiency is the same for all ranks and equivalent to a Rank 3 Ammo Mutation Mod.
The amount of ammo received depends on the equipped weapon and follows the respective mutation mod for the equipped weapon.
Other mutation mods stack with this effect, however the mutation delay will always be applied.
Conversion effect does not work with Atmospheric Archguns.
Trivia[]
Ammo Case was added as a replacement mod for Carrier's  Vacuum precept, with all copies of Vacuum converted to Ammo Case. However, copies of Vacuum acquired after Hotfix: The Vacuum Within 2 (2016-10-06) will not be converted.
Bugs[]
Due to its mutation delay, sometimes it will consume more than enough ammo pickups in range. Sometimes multiple ammo pickups will be consumed even if you need just 1 bullet.
For bows, every shot potentially consumes a lot of ammo pickups within 12m if you have a maxed  Vacuum equipped.
