Black powder shotgun shells are shotgun hulls that use a chemical explosive known as black powder. Black powder is one of the earliest forms of explosives for use in firearms, and it is composed of potassium nitrate, charcoal and sulfur. Each of these compounds has its own role to play.
Potassium nitrate, commonly referred to as saltpeter, is the most important compound in the mixture. This is because it provides the oxygen that is needed to burn the other ingredients. In order to reduce the chances of accidental ignition, the potassium nitrate granules are usually coated with graphite. Potassium nitrate makes up about 75% of the total weight of black powder.
This compound acts as the fuel in the black powder shotgun hull. Though it is simplified as Carbon (C), it is not pure carbon. Therefore, its auto-ignition temperature is much lower. Charcoal makes up about 15% of the total weight of black powder.
Sulfur also acts as a fuel for the shotgun cartridge. However, it lowers the temperature that is required to ignite the black powder. It therefore helps to increase the rate of combustion. Sulfur makes up about 10% of the total weight of black powder.
