context_page_description: The carabine à tige was a type of black-powder, muzzle-loading rifle invented by Louis-Etienne de Thouvenin. The method was an improvement of the invention of another Frenchman, Henri-Gustave Delvigne. Delvigne had developed chambered carbines and rampart rifle-muskets so that when forced against the chamber rim by ramming, the bullet would become deformed and flatten, so as to expand in diameter against the inside of the bore, allowing the bullet to press against the rifling grooves. When fired, the bullet accompanied the rifling and spun. This was an early attempt to work around one of the greatest hindrances to the use of military rifles; in order for a rifle to impart the proper spin to a projectile, the projectile must fit snugly inside the barrel to engage the rifling grooves. The problem, however, was that the black powder used at that time would quickly produce a thick layer residue of fouling. After only three or four shots, a typical rifle would be impossible to reload without using a mallet to force the bullet down the fouled barrel.
context_section_description: The carabine à tige (sometimes called a "stem rifle") was a type of black-powder, muzzle-loading rifle invented by Louis-Etienne de Thouvenin. The method was an improvement of the invention of another Frenchman, Henri-Gustave Delvigne. Delvigne had developed chambered carbines and rampart rifle-muskets so that when forced against the chamber rim by ramming (with three strokes of a heavy ram), the bullet would become deformed and flatten, so as to expand in diameter against the inside of the bore, allowing the bullet to press against the rifling grooves. When fired, the bullet accompanied the rifling and spun. This was an early attempt to work around one of the greatest hindrances to the use of military rifles; in order for a rifle to impart the proper spin to a projectile, the projectile must fit snugly inside the barrel to engage the rifling grooves. The problem, however, was that the black powder used at that time would quickly produce a thick layer residue of fouling. After only three or four shots, a typical rifle would be impossible to reload without using a mallet to force the bullet down the fouled barrel. Delvigne's design addressed this problem by introducing a projectile that was smaller than the bore of the barrel (so more easily bypassing the accumulation of fouling) which after loading could then be struck with a ramrod.  With three strokes of the ramrod, the bullet would become deformed and flatten, so as to expand in diameter against the inside of the bore, allowing the bullet to press against the rifling grooves. When fired, the bullet would accompany the rifling and spin.   This improvement preserved accuracy while reducing the time required for reloading which would otherwise have been necessitated by the heavy fouling.
