Then the next step is to solve the problem of rate of fire.

Naval naval guns have increased their rate of fire to 2 rounds per minute through guide rails and multi-bow bed crossbow recoil devices. In the future, after solving the problems of primers and fixed loading of metal bullet cases, it will be possible to eliminate the need to clean the gun bore and wet the gun bore to extinguish sparks.

By wiping it clean and other steps, the rate of fire can be further increased, and it is possible to reach 20 rounds per minute.

However, the field artillery and mountain artillery used by the Army do not have a re-entry device and require a reset operation after firing a shot. Therefore, the rate of fire is only one round per minute, and it requires the best artillery.

So the next step is to develop an anti-recoil recoil device.

At that moment, Chongzhen drew a sketch and said to Zhang Jimeng: "Zhang Qing, the next step is the recovery device."

Zhang Jimeng has been engaged in firearms research and development for more than five years now and has a considerable degree of firearms thinking. As soon as he saw this recoil device, he knew its usefulness.

"Your Majesty, this re-entry device is truly exquisite."

"With this device, artillerymen no longer have to readjust the elements after firing a shot."

"So, hurry up and build this device." Chongzhen said with a smile, "Then hand over the rifled gun with the recoil device to the arsenal and hurry up for production."
