Thus a rifleman was expected to be able to fire two aimed shots a minute, compared to the four shots a minute for the Brown Bess musket in the hands of a trained infantryman. However, the average time to reload a rifle is dependent on the level of training and experience of the user; twenty seconds (or three shots a minute) is possible for a highly proficient rifleman. Using a hand-measured powder charge for accurate long-range shots could increase the load time to as much as a minute.
