DIY Ammunition Manufacturing (From Scratch)
Making ammunition “from scratch” involves manufacturing the four core components—projectiles, propellant, primers, and cases—rather than simply assembling pre-made commercial parts.
1. Essential Books and Technical Guides
Comprehensive “Total” Manufacturing
- Homemade Ammo: How to Make It, How to Reload It, How to Cache It (Duncan Long): Focuses on manufacturing rifle, pistol, and SMG ammunition from scratch, including chapters on primers, powders, and brass formation.
- Homemade Guns and Homemade Ammo (Ronald B. Brown): Provides step-by-step instructions for simple gunpowder recipes, primer material, and reloading using ordinary hand tools.
- Ammunition Making (George Frost / NRA): A technical, industrial-leaning look at how ammunition is manufactured on a larger scale; provides deep foundational knowledge of metallurgy and chemistry.
Projectiles (Bullet Casting)
- Lyman Cast Bullet Handbook (4th Edition): The definitive resource for casting lead bullets. Covers alloys, mold types, and specific loading data for lead projectiles.
- From Ingot to Target: A Cast Bullet Guide for Handgunners (Fryxell & Applegate): A highly detailed technical resource covering metallurgy, alloy selection, and the physics of terminal performance.
- Cast Bullets for Beginner and Expert (Joe Brennan): A massive collection of technical articles from the Cast Bullet Association.
Primers & Propellants (Chemistry)
- Homemade Primer Course (Obsidian / Aardvark Reloading): A digital guide for reloading spent primer cups using toy caps or “strike-anywhere” match tips.
- The Poor Man’s James Bond (Kurt Saxon): Contains classic instructions on reclaiming chemicals for improvised primers and propellants.
- The Chemistry of Powder and Explosives (Tenney L. Davis): The foundational academic text on the history and manufacture of energetic materials.
| Component | DIY Fabrication Method | Primary Resource |
|---|---|---|
| Projectiles | Casting lead scrap/alloys into molds | Lyman Cast Bullet Handbook |
| Propellant | Mixing Saltpeter, Charcoal, and Sulfur | Homemade Guns and Homemade Ammo |
| Primers | Reusing cups with match tips or toy caps | Homemade Primer Course |
| Cases | Fire-forming or lathe-turning brass | Ammunition Making |
2. Core DIY Recipes (Guides)
Standard Black Powder Ratio (by Weight)
- 75% Potassium Nitrate (Saltpeter)
- 15% Charcoal
- 10% Sulfur Note: Ingredients must be milled separately before mixing and then “corned” (moistened, pressed, and granulated) for consistent burn rates.
Improvised Primer Mix (Matches)
- Tip material from “Strike-Anywhere” matches
- Glass powder (from lightbulbs) for friction
- Shellac/Binder Note: This is corrosive and requires immediate barrel cleaning after use to prevent rust.
3. Safety and Security Mandates
- Ventilation: Lead casting and chemical mixing MUST be done in a high-airflow environment.
- PPE: Eye protection and respirators (specifically for lead vapor/dust) are mandatory.
- Stability: Never store large quantities of homemade primer mix or powder; manufacture only what is needed.
- Corrosion: Most DIY primer mixes are highly corrosive (mercuric or chlorate-based). Firearms must be cleaned with hot water and soap immediately after use.
