"No smoke? It seems that this is really the case, we used to wait for the pungent smoke to clear after the test, but today we don't have that!"

Master Faun reacted, and his eyes suddenly lit up:

"So, we're all going to use this good gunpowder to make ammunition in the future? That's a good thing!"

"I'm afraid it's not right now, this kind of gunpowder is different from the raw material of black powder, the output is still very low, it can't replace black powder, and it still needs some additional processing before it can be applied to the step ***, but there should be no problem with small batches of use in shells."

Xia Lin shook his head and vetoed.

Although the power of fire wool is several times stronger than that of black powder, its stability and combustion rate are not very suitable for use as a propellant alone, and it needs to be processed as a propellant, that is, it is dissolved into a mixed solution of ethanol and ether, and some stabilizers and additional components are added to reduce its combustion rate, so as to give full play to its power.

"It's good to be able to use it in shells, the original 80 breech gun had to clean the chamber for half a day for each shot, and now there should be no problem with this new gunpowder!"

Master Faun was also acceptable to this result, and retreated back to the observation area more than twenty meters away.

Charin also asked the testers to continue the test to see how many shots the current barrel could withstand with a propellant like a cotton wool.

Even the high-carbon steel barrels produced by the steelworks can usually withstand a few thousand rounds of fire, which must take a long time, so Xia Lin had the power of the 80 breech guns using his new twin-base propellant shells start at the artillery test ground on the other side.

Pushing the 80 breech gun to the test position and adjusting it to a 45-degree elevation angle, in order to prevent the new propellant from being too powerful and causing the gun to explode, and the fragments threatening the observation area and the tester in charge of the test, Xia Lin had a sandbag bunker set up near the original firing position, and the tester in charge of the test could pull the pull rope and hide behind this bunker for firing.

"Reload! Shut up! Evacuate!"

「3！ 2！ 1！ Launch!"

With the order of the starter, the tester hiding behind the bunker reluctantly pulled the pull rope in his hand and triggered the mechanism, only to see that the 80 breech gun, which was mounted on the steel and wooden gun carriage, suddenly retreated a distance, and let out a deafening roar, and after the muzzle of the gun rose and fell, a cloud of mud had been splashed on the open field at least six kilometers away in the distance.

"That's not bad power and range!"

Originally, the range of the 80's breech guns, which used black powder and detached shells and propellant packs as ammunition, was only two to three kilometers away, but now after replacing the diatomaceous earth explosives and fire cotton as the main materials, this range has almost tripled, and this result is quite satisfactory to Xia Lin.

Master Faun and his apprentices, who had been dealing with rifles and artillery on the side, and were familiar with the power of black powder, also opened their mouths wide when they looked at this scene, and their faces were full of consternation.

"Boss, this power is not bad, this is simply the same as the heavenly punishment of the gods! So far away, even those elite shooters with pointed ears can't see it, but our artillery can stay in this place and bombard that place! With the Lord of Molten Fire above, the use of this new type of projectile artillery will definitely bring great changes to this continent!" ….

After a long time, Master Faun closed his mouth, picked up the flask with trembling hands and poured himself a few sips of rum, his expression was full of disbelief, and his gaze at Xia Lin was slightly respectful.

"This kind of power can only be called good, Master Faun, the cannonball projectile we are currently using is still a solid projectile made of lead, and when we find a suitable method, we can also cast a shell out of steel or other metal, and then fill the shell with gunpowder.

When our artillery fires the shells at the enemy's positions, the charge inside the shells will explode, so that the shells will gain more lethality!"

Xia Lin was a little helpless at Master Faun's rare and strange exaggerated reaction, explaining his vision for the future structure of the cannonball. Currently post-80s

The shells of the rifled artillery still use solid lead bullets, and such projectiles mainly rely on kinetic energy to kill the enemy, and with the blessing of the speed of hundreds of meters per second, the power is considerable, but it is still limited.

And once Xia Lin researched the appropriate shell structure and fuse, and made a grenade that could explode on the ground or in mid-air at the enemy's position, it could cause more damage than solid lead bullets.

"Charge inside the projectile of the cannonball? It's a scary idea, but isn't it too dangerous? If the shell is shocked or otherwise explodes when fired, it is a bore accident!"

Master Faun swallowed his saliva when he heard Xia Lin's idea, and then asked with confusion.

"This requires us to use a non-explosive explosive charge to fill the projectile! As long as it is properly controlled, the grenade I envision is completely achievable, and when the power of a cannonball from a cannon covers a radius of tens of meters, that is the real firepower!"

Xia Lin, who had the knowledge brought by the other world, naturally understood the doorway, but it was useless to explain it carefully to Master Faun now, so he skipped this topic and asked these testers to continue to test the firing ability of the 80 breech gun.

With the bi-base propellant made of diatomaceous earth explosives mixed with fire cotton, the remnants of the 80 breech gun after firing are visibly reduced to the naked eye, and the usual cumbersome cleaning process of the gun chamber can now be simply cleaned with a bristle brush and dry cotton cloth, so the rate of fire of the gun is increased several times.

"Peng! Peng! Peng!"

On the other side, as the Type 2A rifle continued to fire on the range, the barrel that had not been treated with any other treatment soon let out a mournful "poof!" After a loud bang, the tortured Type 2A rifle exploded.

"How many?"

Xia Lin called the recorder and took the test report in his hand and asked casually.

"Boss, it's 1,173 rounds!"

The tester hurriedly explained.

"One thousand one hundred and seventy-three? It seems that the untreated cotton wool can barely be used as a propellant, but the barrel life is still a little shorter, and I don't know if the Wilkinson boring machine in the machine shop has been manufactured and debugged, and I have to let Master Holguin take the time to make a few gun drills out of pure gold to facilitate the processing of the barrel."
