- When you find weapons, unload them before scrapping.
- There are a couple of places where you can buy ammo.
- Ammo crafting is king.
- Use a variety of weapon/ammunition types across your squad.
If you are running low on bullets, maybe don’t blast away with fully automatic weapons. Go for single shots and try to engage within your weapons optimal range.
Establish milita wherever you can, as they repel attackers they will accumulate loot normally containing weapons and ammo.
Explosives are found in abundance, are powerful and great for conserving ammo.
The different ammo types exist for a reason – its a lot more economical to swap to armour piercing rounds against heavily armoured targets, than dumping mags of average bullets to graze them.
