The only advice I can give is to bring equipment for cleaning. Cleaning your mags is very important as they can cause jams if they're low condition and you can't clean them with the brush like you can your gun. I just got the ouroboro mission on my computer so I'm gonna take it next tide but I've never actually been inside the 2.0 castle. In 1.0 though you couldn't bring enough ammo for the castle mission so I imagine it'll be the same.
Also post your stash.
