Lead-alloy bullets used with gunpowder firearms were unsatisfactory at the bullet velocities available from rifles loaded with nitrocellulose propellants such as cordite.By the late 19th century, lead-alloy bullets were being enclosed within a jacket of stronger mild steel or copper alloyed with nickel or zinc to reliably impart stabilizing rotation in rifled barrels.
Components of a modern bottleneck rifle cartridge. Top-to-bottom: Copper-jacketed bullet, smokeless powder granules, rimless brass case, Boxer primer..

This speeds up the process of loading and reloading the firearm as several rounds can be loaded at once, rather than one round being loaded at a time. COL (cartridge overall length): Factory ammunition is loaded to a standard, SAAMI specified, Cartridge Overall Length so that the ammunition will reliably function in all firearms and action types.
