how do ammo drops work

[JBok]

does certain ammo drop in certain locations
or is it all random

[Faded]

It calculates when you are low and gives you what you need.

[JackieTheDemon]

Everything in a crate/barrel, or dropped from enemies is random. Everything placed in the world or a cabinet is constant.

Rng drop pools are dependent. There are common rng pool, pesetas rng pool, and ammo rng pool.

Common rng pool include
1) Pesetas (Up to 1500)
2) Velvet Blue (Rare)
3) Spinel (Legendary rare)
4) Gunpowder (Usually only 1)
5) Resource S (removed from rng pool when you have even one.)
6) Resource L (removed from rng pool when you have even one.)
7) Green herb (removed from rng pool when you have at least three individual greens / mix include green in your inventory. G+G count as one, G+G+G count as one. The chance% of green reduce the more greens / mix you possess. The third green has low enough chance% comparable to the chance of velvet blue)
8) Red herb (can only appear if you possess none Red herb, and none mix including Red)
9) Ammo (depend on your inventory weapon type and ammo count in reserve, fully loaded weapon type has lower chance% of ammo drop. Example : Non full Striker at 40 shells loaded has much higher ammo drop chance% than full CQBR at 32 rifle.)
10) Hand grenade (does not affected by any mean, chance% is always fixed)
11) Heavy grenade (does not affected by any mean, chance% is always fixed. Does not appear in rng pool until certain point of game progress)
12) Disposable knife (removed from rng pool when you have at least two disposable knife in your inventory. Combat knife, etc don't count. Certain common rng pool do not contain disposable knife at all.)

Barrels give you stuff depending on what you run low on, so if you have low hp you will get a guaranteed herb in your next barrel, and if you have a pistol with no ammo you will more likley get pistol ammo. If all your resources are balanced, you will most likley get money or sometimes a completley random drop.

As for cabinets and such, the normaly guaranteed drops seem to be able to be overwritten by a resource you're running low on. For instance, I once got an herb when low on health in a cabinet that normaly gives shotgun shells. Some drops stay guaranteed tough, like snakes as an example.

Some cabinets are ammo rng pool.

Ammo rng pool means it always spawn ammo, but each time it can be different. You can reload checkpoint / save if the ammo rng pool give you less desired ammo type. You can save schum at ammo rng pool to get higher tier ammo such as shotgun shells and rifle ammo. Its much easier to get desired result in ammo rng pool than other difficult rng pool.

They are affected by chapters, such as smg ammo being absent from the ammo rng pool until you reach chapter 3 (which is the exact point where first time TMP available in merchant shop). Same goes to rifle ammo, they are totally absent in chapter 1.

ok thanks for the info everyone
gonna be useful in my professional run

There are some barrels that are guaranteed to drop specific items. I don't know which barrels/vase/crates etc. But for example, in the village, one of the house's barrel always drops a grenade.

Dropps from enemies should be 100% random drop though.

You shoot, you kill, and then ammo sometimes drops.

Drops for magnum is even rarer, in my 14 hours I got 2 at most leaving me with 6. Crafting the ammo is a waste of gunpowder.

Say this to begin with in your post to start.

[Vinnolo]

ammo spawns are based on your weapons as far as im aware, there are fixed spots of ammo which is what you grab directly from the world (like ammo boxes just laying there), anything that involves crates/barrels and enemies is subject to rng

[1:23]

Does the game take into account your herbs in the inventory? Im always at 40-50% hp but I have 2-3 rgy concoctions ready when needed. I need the game to stop giving me rg herbs, I have like 3 rg concoctions in my inventory rn it’s eating up my inv.

[ggAkatsukiP]

Red herb is not affected by any condition. Its just low% chance of drop. So R can still drop when you don't need it. There's a point I've been, where I have two G+R and four strain of individual R (pain, these stupid Red clog space)
If you still getting G from crate after meeting the requirement to disable them from rng drop pool, then the crate is likely to be fixed drop.
I noticed about crate fixed drop when I'm save schum at chapter 4, where the first crate always spawn handgun ammo even when I don't have a pistol. Hence, not all crates are rng.
Multi drop crate, such as the one before chapter 12 Salazar fight, it contain one fixed drop, one ammo rng pool and four common rng drop. The fixed drop is always handgun ammo and the ammo rng pool can give any ammo depend on your inventory.

Yep, some minor things to add to your very informative post that I've observed. Firstly, red herbs have a 1 count before they stop appearing in the random pool pretty sure. Not sure if the red herb case effects that threshold.

Also, pretty sure handgun ammo is still in the loot pool even if you don't have one on you. Can't avoid it. And sometime during the castle chapters (like chapter 12 is when I first noticed it), magnum can also show up as ammo in the random pool even if you don't own or have a magnum on you. At least, it can past a certain point in the game if you have 0 magnum ammo.

Edit: Also, pretty sure resource S and L both appear less frequently if you have any on you, same goes for grenades. The heavy grenade not spawning in the loot pool at all until some point around or past Verdugo.
