Show the sword, start from the guerrillas

Chapter 86 085, The old squad leader built a shotgun
The blacksmiths worked very quickly, and by the evening of the same day, 10 training grenade launchers made according to the size of the grenade launchers were delivered to the guerrillas' yard.

These training cylinders were very crude and simple. The bottom seat was not the curved one used by the Japanese. It looked very much like the curved bottom plate of the directional blasting device that Li Yuexuan drew for the old squad leader. The upper part of the cylinder was obviously forged. It looked like a round cylinder with a thinner handle connected to the bottom plate.

As for the scale and wrench, there is none of them! In terms of weight, it is 3 kg heavier than the Type grenade launcher.

Fortunately, the training tubes of these grenade launchers are barely usable and are sufficient to overcome the vibration during the explosion.

So, on the second day, and the day after, firecrackers still popped up from time to time on the mountain, sounding very much like the sound of firecrackers during the New Year.

Finally, under Li Yuexuan's observation, these students have mastered the stability of firing, and Li Yuexuan asked them to conduct live-fire shooting training again. And this time, their performance has improved significantly. In the first live-fire, 25 students successfully shot the grenade launcher into the white circle. And in the second live-fire, all of them shot into the white circle.

Li Yuexuan didn’t know if this was the improvement brought about by firecrackers, but since the comrades all achieved satisfactory results, Li Yuexuan was also very happy.

So he moved to another hill, re-demarcated the target area, and conducted live-fire shooting again, but only one shot.

This time, 38 out of 35 people successfully fired their grenades into the target area, and the 3 rounds that missed the target also landed close to the white circle, with a deviation of only a dozen centimeters. At this point, Li Yuexuan felt that these people could graduate, and it would be better to save some ammunition for the organization.

This batch of students graduated, and Li Yuexuan's role as an instructor ended. He felt that he could focus on training the guerrillas. After more than 10 days of training, the guerrillas' new recruits are now training with guns and will soon be able to conduct live-fire shooting training. After this period of grenade launcher training, the Huyan brothers and Bai Dashan are already able to be grenade launcher soldiers.

Li Yuexuan was thinking, with 45 new recruits and 15 veteran team members, why not take advantage of this time to complete the team establishment and form combat effectiveness?

However, the old squad leader seemed to have no intention of letting him go, because the very next day after he sent the students away, the old squad leader found him and took him to the small workshop in the valley over there.

That’s right, the craftsmen brought by the old squad leader have built a small workshop here, with all kinds of craftsmen, and are conducting trial production of grenades and elm cannons.

However, the old squad leader led Li Yuexuan to a workshop and showed him a special weapon.

"Old squad leader, is this modified to look like a rifle?" Li Yuexuan asked in surprise when he saw a shotgun.

"That's right, it was made according to your idea and the simple drawing, imitating the appearance of a large-scale rifle. For this purpose, we also found a master craftsman who used to work in the Taiyuan factory, and then we made this new one! Hey, Xiao Li, what do you think of this thing?" The old squad leader looked very proud. "It can be loaded from the breech, the depth of the barrel is 249mm, the caliber of the barrel is 50mm, the length of the barrel is 1500mm, smoothbore..." Li Yuexuan looked at this thing that looks like a gun, but is actually a cannon, and blurted out a set of data. Then he said: "We still need a tripod, which is a triangular bracket for heavy machine guns. This can be placed on the bracket, and it can be disassembled and carried by each person when marching!"

"Xiao Li, you have such sharp eyes, you can understand it at a glance! We still need time to build the gun mount for the heavy machine gun you mentioned, and we don't have that much material yet! Take a look, do you have any comments?" The old squad leader looked at the shotgun as if he was looking at his own child.

“I really have no opinion, but it would be best to change the buttstock to a two-handed grip like the Min-24. You could even refer to the breech block structure of a cannon and make it more like a cannon. If you don’t mind it being too heavy, you can also add a steel plate shield in front of the tripod to keep the gunner safe.” Li Yuexuan said.

"Your idea is good, but it will take time! Come on, I'll take you to see the big shells we made!" The old squad leader pulled Li Yuexuan to a box and pointed at the orange shells inside, with a proud look on his face: "This is specially made according to the plans you proposed! This shell is made of copper plates and molds, and it took more than a dozen stamping processes to complete it."

"The primer hole at the bottom was drilled directly. The primer powder was made according to the formula you gave, and the filling powder was three taels of black gunpowder, and the front was three pounds of iron sand." said the old squad leader.

"Have you tried it? What's the lethality within 150 meters? Can an ordinary soldier withstand the recoil?" Li Yuexuan asked.

"It's stronger than the one you made yourself, and this is just a shotgun shell. It doesn't have such a high chamber pressure, so it can withstand the recoil." said the old squad leader.

"Then why did you ask me to come? This is great, we can completely mass produce it!" Li Yuexuan said.

"You are an expert, but this is still too heavy, more than 30 kilograms. It is not convenient to carry. Can it be lighter?" said the old squad leader.

"Let me take a look..." Li Yuexuan used the auxiliary panel function to calculate, and then said: "The barrel can be shortened, remove 40 centimeters, keep it at 1100mm, and then the barrel wall thickness can be reduced by 3mm, that is, use a lathe tool to directly remove 6mm of the outer circle, so that it can be lighter. Reducing the weight will make it easier to operate during combat. In this way, the projectile dispersion at 150 meters will be greater, which is not conducive to concentrated fire and killing. But if you go to fight with bayonets after firing a shot, then it will be fine!"

"Hey, let's do as you say! What 150 meters? Can't we ambush within 100 meters? Besides, if we put this in the trench and attack the Japanese assault team, won't we be killed with one shot? Let's do as you say! Lao Guo, don't you have a homemade lathe? Cut it for him!" The old squad leader didn't care at all and made a prompt decision.

"Old squad leader, actually, it can be made smaller, with a shorter barrel, so that it can fire at a range of fifty to sixty meters. However, this is not suitable for field combat, but is most suitable for use in the village! Think about arranging one or two such guns for the comrades in the tunnel, specifically facing the entrance to the alley..." Li Yuexuan reminded the old squad leader not to forget to combine it with tunnel warfare.

"I think your idea is great! Well, you go train, I'll think about it!" After the old squad leader said this, he took a pen and paper and started writing and drawing.
