Muzzleloader Facts

The modern muzzleloader is the product of trial and error over the centuries. It resembles its forebears in loading and basic firing characteristics, but is very different from the first matchlock firearms used in medieval times. The original muzzleloaders were essentially handheld cannons, fired by holding a burning splinter of wood or cloth to the powder hole. Firing methods eventually became more sophisticated, producing matchlocks, flintlocks and the cap-and-ball.

  1. Matchlock

    • The "lock" in flintlock and matchlock refers to the mechanism separating the ignition from the volatile powder. In a matchlock, a small arm held a burning piece of cord; when you pulled the trigger, it swung forward and touched the open dish of powder on the side of the barrel, igniting it. This ignition was carried through a small hole into the barrel, igniting the powder and firing the weapon.

    Flintlock

    • The next technological advancement in muzzleloaders was the flintlock; there was no burning fuse to go out before you needed it, and the powder was partially protected from the elements. A two-part mechanism of the flintlock swung a spring-loaded hammer holding a piece of flint forward against a striking plate, which covered the powder until the last minute.

    Cap-and-ball

    • With the invention of the percussion cap, the technology of firearms changed, making modern cased ammunition and breach loaders possible. It also ushered in the final evolution of the muzzleloader, which is still used by historic firearm enthusiasts. In this version, a small brass cup is hit by a spring-loaded hammer, setting off a small explosion when the hammer strikes the pressure-sensitive chemicals. This released energy is transferred through a small hole into the bore, igniting the powder and firing the ball.

    Accuracy

    • Early muzzleloaders were smooth-bore, highly inaccurate weapons. Later, spiral grooves called rifling were added inside the barrel to spin the bullet and improve accuracy. To create a better seal so the grooves can grip the projectile, a patch of cloth or paper is wrapped around the ball as it is pushed into the bore. This seats it tightly and causes it to grip the walls and spin out when fired.

    Propellant

    • One important evolution in the muzzleloader is the powder used to fire it. The original black powder was made from three mineral substances found in nature. It was highly explosive but not very efficient, since approximately half of its volume was left in solid form and not burned. Modern, smokeless powders are more efficient and safer. They burn at much higher temperatures, making it more difficult for an accidental ignition to happen.
