"The shell of the explosive bullet cannot withstand the high temperature and pressure of the gun barrel, and will explode before it comes out of the barrel. In this way, instead of killing the enemy, it will only blow up itself."

"This is the biggest technical difficulty!" Xu

Chongzhen asked: "Then how are you going to solve it?"

Zhang Jimeng said: "Imitate the concave bullet of the flintlock gun!"

The concave bullet of a flintlock gun is the Mini bullet of another world.

"Concave bullet?" Chongzhen said, "You mean to replace the hollow iron ball with a conical lead bullet and make a conical concave at the bottom of the lead bullet? This is probably not possible because the concave bullet is not insulated.

"

"No, no, no, no lead bullet is needed." Zhang Jimeng said, "We still use the hollow iron ball as the bullet, but we can put a cork under the iron ball. One end of the cork is flat to support the iron ball, and the other end faces

A conical recess is cut out inside, so when the gunpowder explodes, the conical thin edge of the cork will be stretched open by the huge bore pressure, thus tightly sticking to the wall of the cannon bore, and then the hollow shell will be combined with high temperature and high pressure.

The gas is isolated from the gas, and the cork can also be used as a buffer to prevent the hollow iron ball from being squeezed and exploded. In this way, the spent bullet will never self-destruct and can be fired smoothly!"
