After the 32-pounder Caron cannon was test-made, the shooting range became lively, and for many days in a row, the shooting range was full of cannon rumbling, and this new gun was repeatedly tested by a group of gunners.

Through a series of shooting tests, the gunners of the Seawolf gradually figured out the temper and performance of this new cannon, and also found out the maximum charge of this cannon, verified its maximum range, and made a firing table, which was prepared in advance for future equipment on warships.

When this kind of Caron cannon raises the charge to four catties, it takes a 30-degree angle to hang and fire, and can throw a solid cannonball weighing 30 catties to about 500 paces, and when it is 40 degrees, the shell can be thrown 600 steps away, but the dispersion is too large, and it can only be controlled within 400 steps, so it is more certain to hit the target, but this is the data obtained from the test on land, when it is used on the ship, according to the different sea conditions, there will be great variables, and the effective range will be reduced a lot. However, it is estimated that it can basically ensure the shooting accuracy of about 200 meters at a certain elevation angle.

For such a range, although far less than the effective range of the long-barreled artillery, but at sea, such a range is enough, this kind of cannon itself is a killing weapon used when approaching the enemy ship, under normal circumstances will not take a long-distance bombardment with the enemy ship, as long as it can be under the cover of other ships, close to the enemy ship about 100 meters, then you can give full play to the advantages of this kind of gun, whoever meets who is unlucky, even if the Western-style large plywood ship encounters this thing, it will not be able to stand up with a few cannons.

After experiments on land, another newly-minted Caron cannon was cast and transported to the docks, where it was hoisted on the ready-to-be Feizi clipper for testing.

A group of gunners were transferred from the range to the ship and began testing the new gun at sea.

At this time, the No. 3 ship, which had an accident, had been lowered into the water by the ship, and this time the launch was relatively smooth, and nothing happened again.

The No. 1 and No. 2 ships, which were launched first, had already undergone mooring tests, adjusted the ballast stones, and installed sails, and first conducted a sea trial in the interior of the Tamsui estuary, and after no problems, they sailed out of the estuary into the wide water surface of the strait and carried out a sea trial.

Because of the experience of the previous flying clippers, such a trial has become much simpler, the overall center of gravity of the ship structure has not changed much, and a small change will not have any impact on the performance of the ship, so such a trial is much simpler, after the existing problems have been renovated, these boats can be delivered to the sailors for use.

However, the second ship had to stay in Tamsui City for the time being because it was going to test the Caron gun, and after the Caron gun passed the land test, it was loaded onto this ship and began to test it at sea.

For many days in a row, this Feizi clipper was in the sea north of the Tamsui estuary, repeatedly testing the performance of this gun on board.

In the end, the performance of this kind of cannon was standardized, and when it shelled enemy ships on the sea surface, it was best to control the firing range within 150 meters, and if conditions permitted, try to shorten the distance to within 100 meters, and charge four catties, which could hit the enemy ships more accurately.

When using shotguns, the effective range is also about 100 meters, which can exert the maximum effectiveness, as long as the accuracy is not too bad, it can often clear the deck of an enemy ship with a single shot, which is really quite powerful.

Moreover, after this kind of gun was installed on the Feizi clipper, it had little impact on the Feizi clipper, not only could one such Caron gun be arranged behind the mast, but there were also conditions to arrange another one on the bow deck, but the other guns loaded on the ship should be streamlined, and only four No. 5 reference guns could only be loaded on the lower deck, and if there were more, the Feizi clipper would not be able to withstand it.

However, even if the loading of the No. 5 gun is reduced, as long as this kind of ship is equipped with two 32-pounder Caron cannons, it still makes the firepower of this flying clipper quite strong, and the firepower is greatly increased, and once it fights with people, it can exert considerable power.

So Yu Xiaotian immediately ordered the freshwater cannon to be used here, began to mass produce this kind of Caron cannon, equipped the naval division warships for use, and ordered the artillery field to start casting a large number of shells for this new cannon, and to control the tolerance of the shells to the greatest extent, so as not to cause too large tolerances and seriously affect the accuracy of the shelling.

In addition, because of the large caliber of this Caron cannon, it is also more convenient to use some new shells, such as the grapeshotfire that the sea wolf has now been equipped with in large quantities, when using this new cannon to shoot, the power is quite good, if it is used to deal with those Chinese sailing ships commonly used by peers, you can use the grapeshothulet shell composed of twelve small cannonballs directly without solid shells, bombardment of the enemy ship, almost a cannon past, you can basically hit the enemy ship with a thousand holes.

In addition, the large caliber of this Caron cannon also provides great convenience for testing flowering grenades.

In fact, the grenade that can explode in this era has been invented long ago, and it has been adopted in both China and the West, and this grenade is still a round cannonball, and no one in the world has developed thunder mercury, so it is impossible to use a modern fuse device.

The structure of this grenade is very simple, just a hollow round shell, leaving a small hole with a table on it, which leads to the inside of the shell, and the inside is filled with black powder, and in this hole, a hollow wooden plug is inserted, and the wooden plug is filled with slow-burning ignition powder, which is a grenade.

When this kind of grenade is used, it is necessary to turn the mouth of the letter tube towards the bottom of the gun chamber, and rely on the heat energy generated when the gunpowder in the gun chamber is fired, and ignite the gunpowder in the letter tube, and when the grenade flies to the target, it falls to the ground and explodes.

However, this kind of grenade has not been popularized so far, because this grenade has many shortcomings, it is very unsafe when it is first used, and if it is not careful, it may explode when the shell does not fly out of the barrel, causing a serious explosion accident, and the gunner is too nervous in wartime, and may not be able to load the shell correctly into the chamber, resulting in the inability to detonate, and there is a high production cost of this shell, and it is more troublesome to make.

The most important thing is that the power of this grenade is not very large, the hollow shell cannot contain much gunpowder inside, even if it is successfully detonated on the ground, it will not be able to explode many shrapnel, at best, it can explode a few or more than a dozen petals, the lethality is not very strong, and even the power of grapeshotillo may not be compared.

Therefore, in this era, even if this grenade was invented, its use was extremely limited, and the number of large-caliber artillery in the Ming Dynasty itself was not very large, at best, the largest Hongyi cannon, that is, more than a dozen pounds of shells, such shells used grenades, the power is really not good.

But now Yu Xiaotian has made this 32-pound Caron cannon, which makes the cannonball much larger, and on the premise of ensuring the strength of the cannonball, the inside of the cannonball can be filled with more black powder, which can increase the explosive power of the cannonball, making it possible to equip the grenade.

So Yu Xiaotian told the craftsmen in the artillery field about the structure of the grenade, and asked them to experiment with the twelve-pound cannon first, try to make some twelve-pound hollow grenades, and test fire them until they found a mature process and ensured safety, and then tried to make a thirty-two-pound grenade.

In addition, this kind of Caron cannon has a large ballistic curvature, and when shelling the enemy ship at a slightly longer distance, the shells are all falling on the enemy ship in an arc trajectory, and there is no big problem in penetrating the deck of the enemy ship, but it cannot cause greater damage to the enemy ship, so when the battle starts, you can also use incendiary bombs to attack the enemy ship.

As for the incendiary bombs, they are not the kind of hollow shells that can be loaded violently in later generations, but the incendiary shells of this era are actually put on the stove to burn red before the solid shells are used, and then the gunner uses special clips to clamp the red-hot shells and load them into the barrel.

In order to prevent the red-hot shell from causing spontaneous accidents caused by the gunpowder filled in the barrel, before loading the red-hot shell, it is necessary to put a wet mud cake between the gunpowder and the shell, and be very careful not to leak the air, so that the heat of the shell ignites the gunpowder through the mud cake, which is a very dangerous method.

However, this method is very effective for attacking enemy ships, when the cannonballs fall on the enemy ship, in addition to relying on their own weight to cause damage to the enemy ship, the red-hot cannonball can also ignite the enemy ship after stopping, and even burn through the lower deck of the enemy ship, until it falls into the lower compartment of the enemy ship, causing the enemy ship to catch fire.

But such an incendiary shell takes a long time to prepare, to burn the red shell first, it takes a lot of time, but also to prepare a charcoal stove on the ship, which is very dangerous, must be operated carefully, in addition, after the red shell is loaded into the breech, before firing, the gun will be heated, so that the gun heats up quickly, can not continue to shell, must be used after the use of incendiary shells, after cooling the gun body, can continue to fire.

But since this method is effective, Yu Xiaotian still decided not to waste food due to choking, or let the gunners in the Seawolf Naval Division practice the use of this kind of incendiary bombs, train them strictly, and formulate strict operating specifications.

Chen Sheng received this order, and immediately began to make arrangements, and personally began to test the use of incendiary bombs to determine the use of incendiary bombs, and the next step will be to promote the use of the 32-pounder Caron gun in the fleet.

In late February, after some intense preparations, the construction of the road in Tamsui City finally began, and according to the "survey" of the personnel dispatched, they planned a road network with Tamsui City as the center and radiating towards the surrounding migrant villages.

This road network connects all the migrant villages, and in addition to the direct access from the migrant villages to Tamsui City, there are also roads between the various migrant villages.

Moreover, with the participation of Xiaotian, in order to reduce a certain amount of construction, these roads are divided into two levels, the first level of the road is ten steps wide, which can accommodate four ox carts side by side, mainly for the main road for transporting materials, and only reaches the key nodes of the migrant village to ensure that the bulk materials can be unimpeded on this road.

The secondary road is a rural road, six steps wide, which can accommodate two ox carts in parallel, and is mainly used for roads connecting villages and main roads, which can meet the needs of the countryside and easily transport the materials in the village out of the village.
