Wasteland Survivalist: A Scientific Guide to Post-Apocalyptic Survival

With a reference point in mind, Gu Lang began the replication work based on the pictures in the magazine.

Considering that anti-drone rifle bullets are essentially shotgun shells, the requirements for range and accuracy are not high.

Therefore, there is no need to waste the precious Type 191 special ammunition; the old Type 95 ammunition can be used.

The two types of 5.8mm bullets, the old and new ones, have basically the same bullet head.

It has a three-layer structure from the inside out: a steel core, a lead sheath, and a copper jacket.

The outermost copper armor is made of H90 copper alloy, with a copper content of 90%.

The bullet's excellent ductility allows it to fit snugly against the rifling inside the barrel, ensuring stable flight.

To save costs, the Dragon Kingdom army used less copper, and even the bullet casings were made of ancestral painted steel, which contained zero copper.

Gu Lang retrieved several DBP-10 bullets used on the Type 95 rifle and used pliers to remove the bullet heads one by one.

Next, the outermost layer of copper alloy was filed off with a file, and the remaining copper tubing from the refrigerator was mixed in before the copper beads were smelted.

He pulled out the gold-melting tools that hadn't been used in a long time and threw the cut copper shavings into the quartz crucible.

Copper has a melting point of 1083 degrees Celsius, which is 19 degrees higher than that of gold.

The operation method is exactly the same as the previous gold bean melting process: turn on the propane torch to ignite it, and sprinkle borax as a seasoning.

The copper shavings gradually melted into a pool of molten, golden-red copper in the crucible.

He then carefully poured the molten copper into the lead bullet mold.

After cooling, use tools to remove the round copper beads and put them into a plastic container for later use.

The next step is to make disposable spring holders that can hold the copper balls in place. This requires a material that softens when heated and regains its hardness when cooled.

Gulang ultimately chose to use PET plastic bottles, which are common beverage bottles, as the raw material.

Since we don't have a 3D printer, we can only make the molds by hand.

The plastic cartridge is shaped somewhat like a sunflower seed shell, consisting of two parts, top and bottom.

They are identical in shape, and when put together, they can tightly wrap the five copper beads in the middle.

He first used the original bullet as a reference and cut out a negative mold in the shape of half a bullet on the lead bullet mold.

They also picked up a piece of steel pipe from the discarded winch parts and put five copper beads into it to use as a male mold.

He cut the plastic bottle open, flattened it, and cut it into rectangular plastic pieces that were almost the size of bullets.

Seeing that the preparations were complete, Gu Lang immediately began to suppress the sabot.

The first step is to use soapy water as a release agent, applying it to the surfaces of both molds for later use.

The second step is to hold one end of the plastic sheet with chopsticks and immerse it in boiling water for about 30 seconds.

The third step is to quickly place the softened plastic sheet into the female mold and press it firmly with the male mold.

The fourth step is to quickly immerse the entire mold in cold water to harden the plastic bottle again.

Fifth step: Take out the shaped plastic sheet and use scissors to remove the excess.

At this point, half of the plastic cartridge case is complete.

After repeating the above steps, Gu Lang obtained a complete plastic cartridge case.

He inserted five copper beads into it, then pressed the two springs together with his hands until they were tightly sealed.

The anti-drone warhead was then inserted back into its original casing, and rosin was applied to the junction of the warhead and the casing to seal it in place.

An anti-drone rifle shotgun shell has thus been successfully produced.

The rosin he had was leftover flux from soldering circuits when he was making his own infrared night vision device.

In the lousy game Earth Online, clues to breaking through various dungeons are often hidden in seemingly unrelated knowledge.

What seems useless today may be a life-saving skill tomorrow.

When people move forward, they often fail to see the connections between the little things. Only when they look back do they realize how much energy those things they once pondered could have unleashed.

Looking at the first bullet that had been made, Gu Lang wanted to test its effectiveness.

He picked out a large piece from the leftover scraps of waterproof tarpaulin, fixed it to the winch bracket, and made it into a simple target, which he then inserted into the sand next to the boat.

The bullet is loaded into the magazine, propelling the Type 191 rifle forward, and the bolt is pulled to chamber a round.

He retreated to the bow, aimed, and pulled the trigger.

"Bang!"

Five holes burst open on the tarpaulin target.

At a distance of fifty meters, the bullet dispersion diameter is about twenty-five centimeters, and the firepower coverage is significantly better than that of a single bullet.

Gu Lang nodded; the modification was basically successful.

In the following week, he entered the mass production phase, his skills improved, and he eventually modified 210 anti-drone missiles.

All of them were loaded into two 30-round magazines and two 75-round drum magazines.

They are all older Type 95 magazines, stored separately from the new Type 191 magazines to prevent them from being mixed up during combat.

If the plastic bottles on the ship hadn't run out first, he would have wanted to convert all the remaining three hundred old bullets into shotgun shells.

Unfortunately, before they ran out of bullets, they ran out of plastic bottles on the ship.

Fortunately, the nearshore area is heavily polluted, with large amounts of white pollution floating near the sandbar.

He managed to retrieve quite a few plastic bottles; otherwise, he almost wouldn't have had enough for the modification task of 210 bullets.

After finishing these tasks, Gu Lang was finally able to modify and digest the military supplies and ammunition in his possession.

Various supplies and items were converted into actual combat power.

The powerful military equipment brought him a great sense of security, and he began to live a leisurely and comfortable life.

While collecting plastic bottles on the mudflats, Gu Lang discovered that this area was rich in resources, with organisms often bubbling and spewing water from under the mud and sand.

As September arrived, he also ushered in the best time to go beachcombing and get seafood.

There are no nuclear contamination areas nearby and the radiation levels are very low, so you can safely "forage" in the sand ridges.

Every time the tide went out, Gu Lang would put on the water-soaked thermal suit that Wang Bin had left behind, jump off the boat, and dig mud nearby.

There's an old saying, "Eat clams in autumn and crabs in winter," and now is the season for harvesting clams.

Gu Lang moved slowly across the mudflats and wetlands, carefully searching for bulges or tiny radial cracks in the sand.

By tilting an entrenching tool into the sand and turning the entire block over, you can harvest various clams and snails.

You can harvest half a bucketful in just one or two hours, and the variety is quite rich, including clams, mud snails, sea snails, and razor clams.

After each cleaning, place them in clean seawater for 6 hours to allow them to expel the mud and sand from their bodies before cooking and eating.

Due to insufficient sunlight and a lack of plankton in the sea, these seafood items are not considered plump and delicious, but merely edible.

When Gu Lang goes beachcombing, he always comes across a few swimming crabs, but they are too small and don't have much meat, so he releases them.

The blue crabs were quite large, but unfortunately they hid too well, and he had never caught one.

In addition, jellyfish and laver can sometimes be found unexpectedly on the mudflats, which further enrich the food on the dining table in Gulang.
