The 39 in (99 cm) barrel had three grooves, with a rifling twist, and was fastened to the stock with three metal bands, so that the rifle was often called a "three band" model.
The rifle's cartridges contained 68 grains (4.4 g) of black powder, and the ball was typically a 530-grain (34 g) Pritchett or a Burton-Minié, which would be driven out at about 850 to 900 feet (259 - 274m) per second.
These rifles were used by both the United States of America ("Union") and the Confederate States of America!

The black powder at the time quickly fouled the barrel, making reloading slower and more difficult since the balls had to be patched and matched closely to the bore size for rifles.
