Smokeless Powder
- A combustible propellant that sits between the bullet and the primer in the case
- On detonation, the ignited powder rapidly decomposes into a hot, forceful gas that instantaneously expands and propels the bullet out of the gun bore
- The chief ingredient of single-base powder is nitrocellulose
- Double-base formulas use nitroglycerin and nitrocellulose
- Modern powders are a derivative of guncotton (nitrocellulose), which was developed and used in the 1800s in lieu of black powder because it produced less smoke and flash on ignition
- To achieve certain burn rates, powder grains come in different shapes and sizes; they can also have different surface coatings
- Alliant Powder grains are made using an extrusion process and come in cylinder or disc shape
