Beretta A300

The Beretta A300 is a semiautomatic shotgun. When discussing an automatic or self-loading shotgun, it is important to know their categorization. As per their principle of operation, such a weapon could either be recoil operated or gas operated arms.

The Beretta A300 is a gas-operated arm. In such weapons the gas-operated mechanism utilizes the section of the gas pressure in the barrel to move a piston. This reaction in turn operates the action bar and the bolt. When the Beretta A300 is fired it creates a shot charge that is the force of the expanding gases. This then travels up the barrel that is still. As such, the shot charge passes the gas port in the barrel. This is in reality a very tiny and scientifically measured fraction of the gas, i.e., equivalent to less than ¾ of 1% of its total volume. This then passes through the gas port into the expansion chamber. Here, the gas pressure reacts against the piston. Due to this, the piston that is attached to the action bar, forces the piston and the action bar back. This chain reaction forces the unlocking of the bolt.

The Beretta A300 has a built in load adjuster. This inclusion allows one to shoot all 2 ¾ " shotshells interchangeably. This can include, the lightest target loads or the heaviest magnums. Al this is possible without having to make any adjustments. The front of the piston is designed in a manner wherein it is able to expand against the walls of the expansion chamber. This occurs when it is in direct contact to the gas pressure. If the load is heavier then the 'LIPS' of the piston, then it pushes outward. This motion is carried out with the intention of applying more braking power in order to be able to slow down the piston's rearward motion. If the pressure is less, the braking action is less. This in turn helps attain rearward movement at the same rate of speed, not considering the power of the shotshell that is used. As such, prior to the bolt being unlocked and carried to the rear, the shot charge is cleared of the muzzle and the pressures in the barrel is at a safe level.

When the bolt travels back, it hauls and throws out the fired case. As soon as this action is completed, the magazine releases a fresh round. When the bolt and action bar move frontward, the bolt also brings forward a new shell. This is then chambered and the bolt is locked in place ready to be fired again. When the last rounds of the magazine have been used, the Beretta A300 bolt does not lock by itself.

The Beretta A300 has ring shaped grooves that are milled into the outer contour of the piston. As such, the piston brushes the walls of the expansion chamber. This chain reaction results in self-cleaning, which reduces the need to clean the Beretta A300 too often.

The Beretta A300 is a well-styled and quality automatic variety that is useful for all round shooting. Special features of the Beretta A300 are the clean lines and brilliant natural pointing ability; high muzzle velocity that provides quick and accurate shots; greatly reduced recoil; smooth operation that result in minimum wear; reduced number of components; simple takedown and totally trouble free performance.

The Beretta A300 uses the best materials and each piece has been machined and heat-treated to confer to strict standards. As such, the barrel is machined of the finest Chrome Moly steel. The Beretta A300 receiver is made of a singular ERGAL light alloy.
