The full table, with prices and unlock levels for every calibre, is on the ammo page. This article explains how ammo works.
Ammo is bought separately, by calibre, rather than coming with the weapon. Every calibre has the same three types:
| Type | In game | How you get it |
|---|---|---|
| FMJ | Standard | Default on every weapon, no unlock. Bought by the box. |
| HP | Flesh | Unlocks between WARDOG Lvl 6 and 95 depending on calibre, $5,000 where confirmed. |
| AP | Piercing | Unlocks late, Lvl 63 to 140. Prices not confirmed yet. |
12 Gauge also has a fourth type, the Rifled Slug, which unlocks at WARDOG Lvl 41.
Which should I use?
Standard is the best all-round choice and what you'll use most of the time. Switch to Flesh when you're deliberately aiming for arms and legs. Piercing comes so late (Lvl 63+) that for most of your playtime it isn't an option.
What isn't known yet
Damage works on a hit-location model with separate head, chest, stomach, arm and leg zones, but nobody has published the per-zone multipliers or how much armour each type gets through. Until those are confirmed, treat any "penetration tier" figures you see elsewhere as guesses.
