📋 About This Mod
Works with Next Gen Update
Can also be enabled mid save
For Next Gen, use the "Far Harbor and Nuka World" versions of this mod (That same file also works Pre-NG)
What does this mod do?
This mod reduces the weight of all ammunition in Fallout 4 in survival mode.
Comes in 3 versions, 50%, 10% and 150% of the original weight. (50% is the main file)
There is also a plugin for a 50% increase in weight, making all ammo heavier (This was a request that I was more than happy to fulfil.)
This mod will only modify the weight for Base Game + DLC ammunition. It does not touch any creation club values for maximum compatibility.
Notes
I originally made this as I felt that ammunition weight was both too heavy, and that some could be more realistic. A 50% reduction across the board fulfilled the realism aspect, as a few of the ammo calibres are only milligrams lighter or heavier than their real world counterparts.
Installation (And Removal)
I recommend you install using Nexus Mod Manager, however if you want to install it manually just copy the contents of the data folder into your Fallout 4's data folder and make sure it's selected in your Mod Manager / Launcher.

✨ Key Features
📊 Pros & Cons
✅ Pros
- Community-approved with 524 endorsements and over 13k downloads.
- Multiple reduction options let you fine-tune the difficulty to your liking.
- Recently updated (April 2025) so it should work with the latest game version.
⚠️ Cons
- Only affects Survival mode, so if you play on other difficulties this mod does nothing for you.
- No option for a custom percentage—you're stuck with the preset values.
- Potential conflicts with other mods that alter ammo weight or Survival mechanics.
For Fallout 4 Survival players who find the default ammo weight too heavy and want to lighten their load without removing the challenge entirely. Also for masochists who want to make Survival even more brutal by increasing ammo weight. Skip if you don't play Survival or want a more comprehensive overhaul.
💡 Beginner Tips
- Pick the reduction percentage that matches your playstyle—10% is subtle, 90% makes ammo nearly weightless.
- If you're using a mod manager, you can easily switch between the different weight plugins to test which feels right.
- Remember that this only applies to Survival mode, so if you switch difficulties, the effect won't apply.
