To use the Lefoshe cartridge, a weapon with certain features was required. Besides, over the years, hairpin ammunition, in recognition of the merit of the designer, called the cartridge of lefos. In France, such ammunition was called " pin cartridge».
The special design of the ignition system is primarily, availability of studs, gave the new cartridge the corresponding name. No significant innovations in the context of a bullet or powder charge were used. When fired, he had to perform the functions of a striker, transmitting the trigger momentum to the shock train. It was proposed to place a thin rod-pin in the hole and in the open part of the glass. A hole was provided in the opposite wall of the liner. Inside the sleeve, near her bottom on the wall, It was proposed to place a miniature glass-capsule with impact composition for igniting the powder charge. Wafer type sleeve proposed, assembled from metal bottom and cardboard case. A distinctive feature of the latter was the use of a special part., replacement gun head. His version of the unitary cartridge provided for the use of a cylindrical sleeve, in which the bullet was placed, gunpowder and special ignition system. Lefoshe proposed an original solution to such a problem. The main goal of all gunsmiths of that time was to place all the components of the cartridge in one sleeve. Another sample of this kind was patented in 1832 year, and soon the gunsmith proposed a completely new design of weapons and ammunition for him. In the early thirties, he was engaged in the subject of firing weapons, using cartridges with a paper sleeve and individual capsules. A significant contribution to the development of ammunition and weapons for them was made by the French designer Casimir Lefoche. In search of an optimal cartridge design, all the famous gunsmiths took part in their time.
The advent of successful designs has decommissioned less convenient systems., first of all the so-called. Searches eventually led to the appearance of unitary cartridges with central or side ignition, turned out to be very successful and comfortable. Within one compact, a simple and cheap product should be combined bullet, gunpowder, igniter and sleeve. Since the beginning of the 19th century, gunsmiths of leading countries have been searching for the optimal design of a unitary cartridge.
