What is the firing principle of caseless ammunition?

Principle: A caseless ammunition is an ammunition design that forgoes the cartridge case and directly charges the bullet with a solid block that connects or contains the warhead. A caseless round is a type of gun cartridge without a cartridge case. It consists of a combustible binder that is first glued to the gunpowder used for firing, then molded into a solid column (in accordance with the caliber of the special firing), and then the bullet and primer are embedded in the two ends of the gunpowder column, respectively.

Because this particular bullet has no case, the primer works in a different form. In addition to the traditional firing pin firing pin, you can also use electric ignition type primer, gas ignition type primer, the use of the electric arc and high temperature generated when firing, ignition of the column of powder, the rapid expansion of high-pressure gas will be pushed out of the chamber of the bullet head. The shape of the caseless bullet is rather special, with a slender bullet head and a slightly stubby body. When fired, the bullet flies out of the muzzle of the gun, propelled by the gas produced by the burning pillars, while the pillars are burned to ashes.100 rounds of caseless bullets are equivalent to the weight of only 20 rounds of conventional bullets, so soldiers could carry a lot of bullets with them when they fought a war. This invariably increased the sustained combat capability of a single soldier.
