This is a route/method I used to resupply ammo efficiently for the Dieselkraftwerk and achieve weapon mastery level 10.
NOTE: I have noticed some kills just don't register at times. I think this happens more often if you stick an enemy with a shot instead of sticking it to a surface, as in the video I shoot at the ground most of the time.
- using an Ammo Booster helps
- applying at least 3 Tempo weapon attachments increases Max Ammo by 25%
Ammo Resupply location 1 = 0:10
- replay General Winkler mission
Ammo Resupply location 2 = 1:55 (random drops)
Ammo Resupply location 3 = 3:29 (the motherload)
- jump off the Zeppelin/ship to restart mission without going to Catacombs
