Final answer:
Black powder is the only suitable and safe type of powder to be used in a muzzleloader. It was the original gunpowder used in early firearms which saw significant use in conflicts such as the Thirty Years War.
Explanation:
The only type of powder that should be used in a muzzleloader is black powder. Black powder is the earliest form of gunpowder and was the only kind of powder used historically in muzzleloading firearms. It's important to never use modern smokeless powders in a muzzleloader, as they can produce much higher pressures than black powder and could cause the firearm to explode, leading to serious injury.
Muzzleloading firearms saw significant usage during military conflicts such as the Thirty Years War, and their effectiveness greatly depended on advancements in gunpowder technology. Earlier challenges in their development involved keeping the gunpowder dry and handling the procedure of loading lead bullets with a ramrod.
