Answer :
Smokeless powder should not be used in standard muzzleloaders; black powder or substitutes like Pyrodex are the appropriate choices due to safety concerns and the design of the firearm.
The type of powder that should not be used in a standard muzzleloader is smokeless powder. Standard muzzleloaders are designed to be used with black powder or black powder substitutes like Pyrodex. Smokeless powder is much more powerful than black powder and burns at a higher pressure, which can cause severe damage to the firearm and potentially injure the user. Muzzleloaders have been historically used, and the technology has not substantially changed for the replicas and modern versions of historical firearms, hence it is crucial to use the correct type of propellant.
