What type of powder should be used in a muzzleloader?

The appropriate type of powder to use in a muzzleloader is black powder. Black powder has been historically used in muzzleloading firearms since their inception. It consists of a mixture of potassium nitrate, charcoal, and sulfur, which allows for a consistent burn in the relatively low-pressure environment of a muzzleloader.

Muzzleloaders are designed to operate under specific characteristics set by black powder, including how it ignites and burns. Using smokeless powder or other types of powders, like cordite or detonating powder, can be extremely unsafe, as these are formulated for modern cartridge firearms that are built to withstand higher pressures. The mismatch in the intended use of the firearm and the type of powder can lead to catastrophic failures such as explosions or misfires.

In summary, black powder is the safe and effective choice for muzzleloaders, adhering to historical practices and ensuring the firearm operates correctly and safely.
