The Benelli Raffaello semi-automatic shotgun is manufactured by Italian arms manufacturer

Benelli Armi SpA Benelli Armi SpA is an Italian firearm manufacturer best known for shotguns used by military, law enforcement and civilians, located in Urbino, Marche. Founded in 1967 as an offshoot of the Benelli motorcycle factory that sold motorcycles throu ...

Design details

The shotgun has a relatively small number of component parts, incorporating a simple operating principle. The main features of the mechanism are the turning block bolt locking system and the cartridge feeding system (cut off).

Operation

Benelli's range of semi-automatic shotguns operate on the same basic principle of

inertia Inertia is the idea that an object will continue its current motion until some force causes its speed or direction to change. The term is properly understood as shorthand for "the principle of inertia" as described by Newton in his first law ...

kinetic energy In physics, the kinetic energy of an object is the energy that it possesses due to its motion. It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity. Having gained this energy during its accele ...

breech block A breechblock (or breech block) is the part of the firearm action that closes the breech of a breech loading weapon (whether small arms or artillery) before or at the moment of firing. It seals the breech and contains the pressure generated by th ...

inertia makes it move about 4 mm forward in relation to the power of the cartridge, compressing the spring. When this is fully compressed, it overcomes breech block inertia, thrusting it to the rear under residual pressure, permitting cartridge case extraction and reloading with the conventional system. The pressure of the spring is calculated to delay the opening of the action, which occurs after the shot has left the barrel, and to regulate the different pressures produced by cartridges of varying power, with no need for braking.
