    The 1842 Springfield was originally loaded with 110 grains of powder and a 412 grain round ball giving a muzzle velocity of 1,500 f.s.

    The 1855 Springfield Rifle-Musket was loaded with 60 grains of powder and a 500 grain Minié ball giving a muzzle velocity of 950 f.s.

    Both velocities were measured with ballistic pendulums back in the day.

    However, there was an 1842 and 1847 Musketoon with the barrel cut down from 42 to 26 inches, and there were many .58 caliber carbines, such as the Cook and Brother, Tallassee, Richmond, etc., with barrels around 24 inches.

    What kind of velocities would the shorter barrels produce with the same loads?
    And were lighter loads specified? 110 grains seems excessive even in a full size musket.

    My guess would be about 150fps less. That's just my opinion.

    muskets lose velocity differently than smokeless rifles.100 grains of 2f produces 1195 fps with a 505 grain buffalo bullet in a 3 band enfield.the musketoon produces 1115 fps with the same load.so from a 39 inch barrel to a 24 inch barrel is a loss of 80 fps.i got this information from sam fadala's 4th edition of the blackpowder loading manual.with my chrony my results were very close to his.

    Boy, I bet that would be fun to shoot in my little Musketoon.
