Smokeless powder is a type of propellant used in firearms and ammunition. Unlike traditional black powder, it produces little to no smoke when ignited, allowing for better visibility and accuracy during shooting. This makes it a preferred choice for modern firearms. The main components of smokeless powder are nitrocellulose and sometimes nitroglycerin. These materials burn more efficiently than black powder, generating higher pressures and velocities. Smokeless powder is essential for various applications, including military operations, hunting, and sport shooting.
