The Benelli Raffaello semi-automatic shotgun is manufactured by Italian arms manufacturer Benelli Armi SpA
.
range of semi-automatic shotguns operate on the same basic principle of inertia
l operation, with a fixed barrel, utilizing the kinetic energy
of gun recoil
. This system requires no outlet for gas or barrel recoil, but operates by means of a spring
freely interposed between bolt head and bolt.
During firing, due to the recoil of the gun, breech block 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.

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

Inertia
Inertia is the resistance of any physical object to a change in its state of motion or rest, or the tendency of an object to resist any change in its motion. It is proportional to an object's mass. The principle of inertia is one of the fundamental principles of classical physics which are used to...

Kinetic energy
The kinetic energy of an object is the energy which 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 acceleration, the body maintains this kinetic energy unless its speed changes...

Recoil
Recoil is the backward momentum of a gun when it is discharged. In technical terms, the recoil caused by the gun exactly balances the forward momentum of the projectile and exhaust gasses, according to Newton's third law...

Spring (device)
A spring is an elastic object used to store mechanical energy. Springs are usually made out of spring steel. Small springs can be wound from pre-hardened stock, while larger ones are made from annealed steel and hardened after fabrication...
