A black powder cartridge is a type of ammunition that uses black powder as its propellant. Black powder, also known as gunpowder, is a mixture of saltpeter (potassium nitrate), charcoal, and sulfur. While black powder was historically the first form of smokeless propellant used in firearms, it has largely been replaced by smokeless powder in modern ammunition due to its higher energy density and efficiency.
