Answer:
A bullet that could be loaded quicker and fired more accurately
Step-by-step explanation:
This was a type of bullet developed by the French army officer Claude-Etienne MiniƩ, in the year 1849. It was used during the American civil war. MiniƩ developed this bullet because tradidional ammunition had to engage the spiral grooves, or rifling, inside the rifle barrel, had to be equal in diameter to the barrel, and shooters would have to jam the bullet into the rifle by force. Because of this the rifles would become increasingly difficult to load as the barrel became dirty with gun powder residue. This bullet was smaller than the diameter of a rifle barrel, and could be easily loaded, even when the rifle became dirty.This gave rise to the ammunition that we see today. :)
