Modern smokeless powder can cause serious injury if used in a muzzleloader because it is specifically designed for use in modern firearm cartridges and operates at much higher pressures than black powder or similar substitutes. Muzzleloaders are designed to handle the characteristics and pressures associated with black powder, which burns at a slower rate and produces lower pressure. When smokeless powder is used in a muzzleloader, it can lead to dangerous overpressurization, which might result in catastrophic failure of the firearm, potentially causing severe injury to the shooter and bystanders.

In contrast, black powder and substitutes like Pyrodex are made to be safe for use in muzzleloading firearms, assuming they are used correctly and within the intended parameters. Granular powder refers to a more general category, but if indeed referring to a type suitable for muzzleloaders, it would not pose the same risks as smokeless powder. Thus, the dangers associated with smokeless powder highlight its incompatibility with muzzleloaders and the severe consequences that can follow its misuse.
