The Benelli Raffaello semi-automatic shotgun is manufactured by Italian arms manufacturer
Benelli Armi SpA.
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 o ...

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 a ...

Recoil (often called knockback, kickback or simply kick) is the rearward thrust generated when a gun is being discharged. In technical terms, the recoil is a result of conservation of momentum, as according to Newton's third law the force r ...
. This system requires no outlet for gas or barrel recoil, but operates by means of a
spring
Spring(s) may refer to:
Common uses
* Spring (season), a season of the year
* Spring (device), a mechanical device that stores energy
* Spring (hydrology), a natural source of water
* Spring (mathematics), a geometric surface in the shape of a h ...
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.
