    “Smokeless powder’ (new as in 1890’s). Smokeless powder is not merely a mixture of components like blackpowder is. It is a chemical compound, a nitrocellulose based propellant, though highly combustible, is not actually classed as an explosive the way blackpowder is.

    When compared to blackpowder, smokeless powder offers far less smoke, far less fouling, between two and three times the power (depending upon the powder brand), and subsequently higher velocities, in addition to much higher chamber pressures. While blackpowder is measured by volume, smokeless is carefully measured by weight.

    Different blackpowders generally only vary in the fineness of the flake size (the corn size) and the quality of manufacture. Regardless of that, blackpowder is still just blackpowder, with the same ingredients in the same proportions.

    Smokeless powders, however, are all different blends, each of which are formulated as per their intended use. Different smokeless powders are made specifically for pistol cartridges, others specifically for rifles, and others specifically for shotguns. Because shotguns and pistols are both low pressure types of rounds (a 12 gauge shotgun shell has about half the chamber pressure of a .22LR rimfire round), some smokeless powders are dual use, intended for use in either pistol or shotgun ammo.” – Before it’s News

    From Outdoor Hub:
    “This incident occurred in Martin County, where an unidentified man poured smokeless powder into a black powder-only muzzleloader. What resulted was the firearm exploding like a grenade and ripping off the man’s fingers.”

    Never, never, never use smokeless in a Black powder only firearm.
    Ever.

    Something tells me they were mixing alcohol with their powder as well.

    IIRC, there is only one muzzleloader on the market made to take smokeless powder. It’s out of production now, and it was made on limited production runs by Savage. It uses smokeless powder intended for shotguns. It’s the Savage Model 10ML-II, a .50cal, bolt action, inline muzzleloader.

    In short, smokeless powder produces between 2x to 3x the pressure (depending upon the powder) of blackpowder. Using smokeless in a weapon designed for blackpowder is foolish.

    My knowledge of and experience with such weapons is limited. Could you not just use 1/3 or 1/2 the amount of smokeless to get the desired result?

    No.
    The powders burn rates are different, the pressures involved are different, the speeds at which the pressures are generated are different.

    Smokeless burns hotter, faster and at fairly predictable speeds.
    Black powder, slower, with less pressure and often variable results depending on many variables.

    There are ample supplies of black powder for shooting black powder firearms. There is absolutely no reason to consider dangerous experimentation.
