SHOWER contraction

A major problem with shotgun shooting is the onset of a burst of shotgun just outside the barrel. This is largely due to the mouth pressure that pushes the light spacer plug toward the shotgun when the resistance caused by the shotgun is reduced as the shotguns come out of the barrel. A method for controlling this is to reduce the barrel diameter just outside the barrel mouth. Stenosis slows down the speed of the stopper so the shotgun gets further away. However, mechanical shrinkage causes the shots to be strongly pressed against each other, resulting in individual shots becoming vague and complex. This also causes an indeterminate flight path. The flock of bullets will not expand conically, but more strongly. Due to their hardness, steel shafts retain their shape better but also compress less and cause much greater strain on the barrel. Weapon manufacturers often prohibit the use of maximum clamping on steel rifles. The plastic shotgun also reduces the scattering of the shotgun, but when using a hard shotgun, it has to be made very thick so that no shrinkage occurs. : Too much impact work. Shots may even stick to plastic and partially fly like a bullet.

I <<·· / Reducing the barrel diameter also makes it difficult to use the shotgun m t: · ϊ · as a bullet firing weapon. Changing the contraction is i.i: very difficult with old shotguns and even with new ones often requires the use of a tool.

Suitably strangling the outlet mouth (4) after the actual barrel mouth provides a powerful gas jet radially blowing toward the center line of the barrel, which collects • · ·; ··: past the swarm without mechanical contact. The pressure behind the stopper is then significantly reduced, thereby also reducing the breakdown of the shotgun.

The method allows stepless adjustment of the "contraction" by varying the area of the gas flow opening. With the right mechanism, the shooter can quickly change the "contraction" even between double shots. In addition, nozzles of different shapes can be replaced at the outlet. The method also does not exclude the possibility of using existing shrink sleeves, especially if the method is applied to a separate attachment to be threaded into the shrink sleeve. By using a suitably shaped throttle nozzle, shotguns can also be fired from a rifled barrel or made into a shotgun oval. The weapon can easily be returned to its original state if desired.

Lightweight material (bismuth, steel, etc.) is most affected by strong gas flow. The slower firing powder used in magnesium cartridges produces a stronger mouth pressure as well as a cartridge firing from a shorter barrel. These considerations enhance the advantages of this method over normal contractions because the guiding flow is more intense. The method allows a thinner shotgun to be used, or even omitted, to allow more lightweight shots to fit in the cartridge. The method allows the weapon to be quickly adapted to various shooting conditions without the use of tools.

'' In Publication 2, the use of blades that are indeterminately vibrated by mouth pressure is intended to provide a bullet pressure effect that diverges randomly from a direct trajectory to provide an increased scattering pattern, mainly by serial firearms, to improve the probability of hit.
