[0002] The shotgun is a kind of breech-loading weapon which can launch multiple projectiles or bullets, and has the characteristics of large caliber, fierce firepower at short distance and high hit probability, and can implement saturation shooting on the target. In mountainous, jungle, town and street battle, the shotgun has more advantages. In the past wars, the shotgun can be seen everywhere, but it cannot become the main weapon of the infantry because of the short effective range. However, with the change of the world situation, the form of war has also changed, and the combat tasks of the military and police forces have been shifted to coping with local conflicts, fighting against terrorist activities and stopping violent crimes, and the combat characteristics of the shotgun in specific scenarios can be fully played.

[0039] In combination Figure 2 , the coil 7 is wound on the coil groove 4-5 outside the shell 4, and enters the shell 4 through the coil hole 4-6 to connect the ignition head 9.

[0040] In combination Figure 2 , Figure 3 , the sealing ring 8 and the ignition head 9 are placed in the ignition cylinder 4-8, the sealing ring 8 is on the outside and plays a sealing and limiting role, and the ignition head is on the inside and directly ignites the gunpowder through the ignition hole 4-9.

[0041] In combination Figure 2 ,Figure 10 The base 10 and the tail of the cartridge case 4 are connected by threads to form a seal; the base 10 has four gunpowder gas holes 10-1, and when fired, the gunpowder gas is discharged from the gunpowder gas holes 10-1 to propel the shot; the base 10 is provided with external threads 10-2, which are threaded to the internal threads 4-11 of the cartridge case 4.

[0042] Combination Figure 2 , Figure 3 The sealing gasket 11 is a low-melting-point plastic gasket, which prevents gunpowder leakage during loading and melts at the high temperature of the gunpowder gas during firing, allowing the gunpowder gas to pass through the gunpowder gas hole 10-1.

[0043] The shotgun in this embodiment uses a metal storm electric firing method and a series ammunition placement system. During loading, shotgun I and shotgun II are respectively the first-firing shotgun and the second-firing shotgun. The two are connected end to end by a threaded connection and placed in series in the barrel. By adjusting the strength of the threaded connection, shotgun II cannot break free from the threaded connection at the rear, and the threaded connection between the two can be made to fail just when it is fired.

[0044] Combination Figure 11 Upon firing, the coil on the outside of the barrel is energized, generating a change in magnetic flux. This change in magnetic flux, through electromagnetic induction, energizes coil 7. The current in coil 7 causes the ignition head 9 to discharge, directly igniting the gunpowder in the chamber 4-10 through the ignition port 4-9. The resulting high-temperature, high-pressure propellant gases melt the two sealing gaskets 11 and act on the baffle 4-3 in the middle of the cartridge case 4. Simultaneously, the propellant gases act on the cartridge base 10. Because the effective area of ​​the baffle 4-3 in the cartridge case 4 is larger than that of the cartridge base 10, the propellant gases create a pressure difference on the shotgun shell. The resultant force on the shotgun shell is forward, causing the shotgun shell I to move forward within the barrel. As the shotgun shell I moves forward, some of the propellant gases act on the sabot 5, giving it additional power. This causes the sabot 5 to begin separating from the cartridge case 4 during its forward movement. The sabot 5 and cartridge case 4 completely separate as the shotgun shell I exits the barrel. As the sabot 5 begins to separate from the cartridge case 4, some of the propellant gases pass through the gap between the sabot 5 and the baffle, through the propellant gas holes 4-12, and into the ignition guide 6. This gas acts on the sealing plate 2, causing it to separate from the sabot 5. The bullet 3, no longer obstructed by the sealing plate 2, can then fly forward in various directions, completing the shotgun's attack on the target area. Shotgun shell I, under the influence of the propellant gases, breaks free from its threaded connection with shotgun shell II. Shotgun shell I completes its firing action upon exiting the barrel. Shotgun shell II is fired in the same manner, moving within the barrel until it exits. Subsequent shotgun shells are fired in this manner.
