The safe type of powder to use in muzzleloaders is blackpowder or blackpowder substitutes. Muzzleloaders are designed specifically to use these types of propellants, which include traditional blackpowder made from saltpeter, charcoal, and sulfur, as well as modern substitutes that are formulated to provide similar performance with potentially less residue and improved safety characteristics.

Blackpowder and its substitutes burn at a rate and produce pressure that are appropriate for the design of muzzleloading firearms, allowing for safe and effective operation. These propellants also have the characteristic of being able to ignite reliably with traditional ignition systems used in muzzleloaders, such as percussion caps or flints.

Using other types of powders, such as smokeless powder or commercial gunpowder, can result in dangerously high pressures that the muzzleloader is not built to handle, leading to potential catastrophic failure of the firearm and risk of injury to the user. Therefore, it is essential to stick to blackpowder or suitable substitutes that align with the design and operation of muzzleloading firearms.
