AMMUNITION
_______________
Ammunition replacements
- Virtually all vanilla and DLCs ammunitions have been replaced. Red content is from the CORE - Ex.
- Non ballistic and energy ammunitions have been completely removed from loot, vendors and are not manually placed anywhere.
![](https://staticdelivery.nexusmods.com/mods/1151/images/76189/76189-1709162836-1149057437.png)
- Ammunition not replaced/removed:
- Fusion cores - Used in power armor.
- Greatly reduced the ammunition spawned with firearms (loot). 1-5 bullets maximum depending on the caliber.
- Point Lookout is a great place for finding and buying high caliber ammunition. Plus .32 ACP and BB. (CORE - Ex.)
Caliber stats
- Custom caliber damage: Your caliber will determine the damage you will inflict regardless of the firearm.
- Custom real world weight in Grams. For example, 10mm Auto = 9.6g, .44 Magnum = 18g, .50 BMG = 46g.
- Custom values for selling and buying.
- Custom effective range in combat regardless of the firearm. Refer to Range and damage example section.
- For even more stats, refer to the Customizations section.
![](https://staticdelivery.nexusmods.com/mods/1151/images/76189/76189-1709237327-1357539635.png)
Customizations
- You can fully customize your firearm in a lot of different ways, using different Calibers, Ammo Types, Receivers, Barrels, Muzzles, Scopes, Grips and Stocks. This is a list of possibilities and effects:
- Calibers: Damage, armor penetration, ammo weight, stagger effect and exploding limbs/head, range, recoil, accuracy, impact force, speed and gravity. And some effects like Bleeding and Crippling.
- Ammo Types: Damage, armor penetration, range, recoil and accuracy. And some effects like Incendiary, Radiation, Poison, Explosive, Bleeding and Crippling.
- Receivers: They will mostly affect damage.
- Barrels: They will mostly affect range, recoil and accuracy.
- Muzzles: They will mostly affect range, recoil and accuracy.
- Scopes: They will mostly affect accuracy.
- Grips: They will mostly affect accuracy.
- Stocks: They will mostly affect accuracy.
- These perks will affect your firearms:
- Pistols (Gunslinger).
- M249 SAW (Heavy Gunner).
- The rest of the firearms (Rifleman if fire mode semi-auto is selected and Commando if fire mode auto is selected).
- Other considerations:
- When modifying your firearm, using the ammo type "Snake Shot" or using the caliber "BB", will change some statistics accordingly to behave like a shotgun.
- When using the caliber .50 BMG in your SPAS-12, will change some statistics accordingly to behave like a rifle.
Range and damage example
This is an example of how different calibers and attachments can affect range and damage falloff.
![](https://staticdelivery.nexusmods.com/mods/1151/images/76189/76189-1703930592-1064877440.png)
- From our point of view to the target dummy is represented the minimum range and its maximum damage values of most small calibers before starting to gradually falloff.
- Taking the place we are in the picture as reference, if we move farther away until doubling the distance from the target dummy, our damage will go decreasing until reaching the maximum range and its minimum damage values.
- Shotgun shells suffer the most from these damage penalties, losing up to 75% damage when out of range (when the maximum range is surpassed).
- Small calibers damage penalties going from 30-40%.
- Medium calibers damage penalties going from 20-30%.
- High calibers almost have no damage penalties, going from 10-20%.
- These ranges data is represented in the Caliber stats and Customizations above sections. Keep in mind, you can modify the ranges to your liking, using different combinations of calibers, ammo types, barrels and muzzles.
Tweaks
- Thanks to the original authors who gave me permission to integrate these game settings, they are down below in the credits.
- Improved ragdoll force.
- Increased bullet holes time, distance and amount before they disappear.
- Increased shell casings time, distance and amount before they disappear.
- Deleted Sneak status damage buffs with guns and explosives. (You will still see the status, but has no effect).
- Deleted the Adrenaline perk damage buffs. (You will still see the perk, but has no effect).
- Super Mutants can equip and hold two handed Combined Arms' firearms.
- Deleted Critical damage. (You will still see the option inside VATS, but has no effect).
- Enemies' limbs will no longer explode in a gore fest, that can only happen with high calibers and some shotgun shells.
- Melee firearm attack time is now determined by the weight and size of your firearm.
- Tweaked the size and range of your flashlight light beam, it behaves now like a real flashlight.
- Vertibirds' miniguns use some statistics of the 7.62x51mm NATO caliber, like the damage, range and projectile physics, but not the bleeding effect.
16 new magazines
- G36 (7.62x51mm NATO 100rnd)
- MK12 (7.62x51mm NATO 50rnd)
- M249 SAW (7.62x51mm NATO 200rnd)
- FN P90 (.45-70 Springfield 50rnd)
- ASVAL (7.62x45mm 30rnd & 60rnd).
- M9A1 (.32 ACP 10rnd & BB 6rnd) (CORE - Ex.)
- M1911 (.32 ACP 10rnd & BB 6rnd) (CORE - Ex.)
- Makarov PM (.32 ACP 10rnd & BB 6rnd) (CORE - Ex)
- PL-15 Lebedev (.32 ACP 10rnd & BB 6rnd) (CORE - Ex.)
- TT-30 Tokarev (.32 ACP 10rnd & BB 6rnd) (CORE - Ex.)
- 7.62x51mm NATO caliber rounds break upon impact causing severe damage and internal bleeding, so it fits perfectly the M249 SAW because the bleeding stacks. Also this caliber has great damage, more recoil and the highest of the rates of fire.
- .32 ACP caliber has good damage and is armor piercing. (CORE - Ex.)
- BB caliber pellets have great damage if all the projectiles hits the target. It's like having a shotgun in your pistol. (CORE - Ex.)
Craft/scrap ammunition
(even the added from Point Lookout! (CORE - Ex.))
- Chemistry Workstation > Equipment And Crafting Overhaul > (Craft it) Universal Workbench.
- Under Ammo Station you will find these options: Ammo Craft x10, Ammo Craft x100 and Ammo Scrap x10, Ammo Scrap x100.
- Depending on the caliber, you will need different materials for crafting your ammunition.
Choose ammunition
- Weapons Workbench > (Select a firearm) > Magazines.
- Obviously not every ammunition is available on every firearm, most have unique choices.
- Depending on the magazine, you will need different materials for crafting it.

Firearms replacements
- Virtually all vanilla and DLCs firearms have been replaced. Red content is from the CORE - Ex.
- Firearms' Customizations (every possible combination of attachments) are fully randomized and distributed amongst all NPCs and companions regardless of your level or theirs since level 1.
- Rail attachments are not randomized, because due to game engine limitations, when NPCs holster their firearms with the flashlight turned on, they may cast light beams all over the place. But I included an optional tweak that randomizes rail attachments too.
- You can customize this firearms' list to your liking, refer to the F.A.Q. for a tutorial.
![](https://staticdelivery.nexusmods.com/mods/1151/images/76189/76189-1702573335-386584488.png)
- Firearms and their ammunitions not replaced:
- Alien Blaster Pistol/Hub's Alien Blaster - Alien Blaster Cell. Because they are aliens and don't use a G36.
- Thirst Zapper - Squirt of Water/Nuka Cola. Required at some point of the DLC Nuka World.
- Flare Gun - Flare. Required to call The Minutemen for help.
- Paddle ball - Ball string. For the lols.
- Unique firearms - They all have attached a Legendary effect and some show a visual glitch if replaced. Therefore some Unique firearms have not been replaced, simply you won't be awarded with any firearm at all or the firearm won't spawn in its usual location.
- Firearms cannot be crafted, it would be too easy since you have plenty of ways to obtain them, like enemies dropped loot, general loot and vendors.
- You can modify your firearm and craft/scrap ammunition without perks requirements, only materials.
- NPCs don't drop their weapons when killed. This way you cannot loot a full magazine for free.
Companions' firearms replacements
- Special and Companions' firearms are replaced too, for example: Cryolator or Piper 10mm Pistol.
- Companions have non-playable default firearms with unlimited ammunition and fully randomized.
- You cannot take these firearms away from them.
- If you want to replace the non-playable default firearm with one of your liking, equip them a new firearm and its ammunition.
- If your companions run out of ammunition of the firearm you equipped them, they will swap to their original non-playable firearms. This is a vanilla behavior, but now with Combined Arms firearms.

Known conflicts
CAT makes redundant some of the mods you have been using until now, because CAT fully or partially replaces their mechanics.

Compatibility patches
When selecting some calibers or ammo types for your firearms, you can choose between 3 different types of armor piercing, [AP], [AP+] and [AP++].
- [AP] deals 25-65 armor piercing points. Increased chance to penetrate standard helmets.
- [AP+] deals 65-75 armor piercing points. Will always penetrate standard helmets.
- [AP++] deals 75 armor piercing points. Can headshot almost anything at close range, including power armor and deathclaws.
For the SPAS-12 shotgun you need to change your shells to the.50 BMG caliber.
Additional notes:
- No matter what combination of attachments you choose, if one attachment provides [AP++], it will override [AP] and [AP+] of any other attachment.
Combined Arms Tweaks (CAT) has a patch for using the "reload" and "magazine" mechanics of Bullet In The chamber 2 Beta.
- SPAS-12: You cannot drop a full clip while reloading (BITCh 1) and can use the Pseudo-Magazine System (BITCh 2).
Combined Arms Tweaks (CAT) has a patch for using the "holster" mechanic of Flashlight Holster.
- It allows your firearms' flashlight to automatically be turned off when holstered.
Additional notes:
- If used together with CAT Random Rail Attachments, NPCs' firearms can have flashlights attached too, and due to the game engine limitations, when NPCs holster their firearms with the flashlight turned on, you will see light beams all over the place.
Combined Arms Tweaks (CAT) has a patch for using the seamless "canted sighting transition" mechanic of Side Aim Framework.
- It allows you to aim using your scope or the side of your firearm.
Additional notes:
- Not all Combined Arms firearms were available for this patch, because they lack some animations that Side Aim Framework mod requires.
