Both advancements in ammunition's bullet and its cartridges for shoulder arms enabled advancements in carbines to be practical and feasible. Both rifling and breechloading were greatly influenced by the changes in ammunition. Ammunition advancements would be just as important as the carbine's advancements, because they influenced what the design of the carbine will be. According to Felicia Johnson Deyrup, "Improved ammunition was an integral part of the development of breechloading arms."1 As ammunition improved, so did the carbines and rifles that used them.

​

Not only did the marksmen spend less time loading his gun, and even possibly cleaning it, he became a better shot. Although the final product of both the bullet and cartridge were successful for both the manufacturers' inventors and the gun users, there would be many failed ideas.
