Buying an air gun has many advantages. For example, air guns are very accurate, quite powerful and available in large calibers. In addition, you can also shoot air guns nice and quiet, as long as you use the right silencer. You have to ask yourself: what makes an airgun so special in the world of windbreakers? And why is it actually called a PCP rifle? Airguns, also known as PCP rifles, are the so-called The Pre Charged Pneumatic, like other rifles, is named after the type of system. These rifles have a cylinder that you fill with compressed air in advance using a pump, scuba cylinder or compressor. Advantages? Extremely accurate shots at long distances (from 50 to even 300 meters!) and multiple shots without reloading.

Did you know that large-caliber air guns are used for hunting in America? Of course! With a powerful air gun, you can shoot a deer and even game. Note! In the Netherlands it is strictly forbidden, here air guns are rarely used for hunting and then only for pest control by recognized hunters and fighters who have an exemption for it.

You can buy an air gun with any type of magazine. This means that you can buy both an airgun with a magazine, an airgun with a CO2 magazine and an airgun with a magazine. Very convenient as magazine firing avoids awkward fiddling with small bullets between shots. This is also an advantage of shooting with a magazine air rifle, you can fire several shots in a row while still aiming at your target. This way you will keep your concentration and the next shots will be much more accurate.

Nowadays, there are even stock breaks such ascrazier,REP-10zRoadsterGAMO models. These rifles feature clever technology that ensures the bullet is pushed into the chamber at a nod. This way you can have a few magazines ready and keep shooting.

Springers are airguns that use a spring-driven piston. The spring engages by rocking the barrel and flexing it until you hear a click. Then you put the pellet into the bent barrel and straighten it again.

The most famous air rifles are Springers. These are rifles that use a price-driven piston. By fully "bending" and bending the barrel until you hear a click, you tighten the spring. Then you put the pellet into the bent barrel and straighten it again. Because of this phrase, the rifle is often referred to as a bent-barrel rifle or a kinked rifle.

Shooting stance

When firing, the rifle moves back and forth due to the mechanical movements of the spring and piston. Most rifles are built in such a way that a good shooter can hold the rifle in one place during this movement and aim well at the target. It is important to learn such a position that the recoil of the rifle always has the same effect. Consistent training and practice makes perfect in this case as well. This, of course, is relevant for people who like to improve their skills, for example, by participating in contests or competitions. Once you learn to shoot an airgun well, you can generally shoot other types of rifles as well, so you're not increasing your skill with one type of rifle when you practice with a spring-loaded rifle.

Hit

Most shooters are generally recreational or occasional shooters. This means you probably spend less time practicing shooting and aiming for fun. Some spring-loaded rifles have a fairly violent recoil that makes it difficult to hit. This can lead to situations where fun turns to frustration and the rifle is eventually put away. Especially slightly better air guns give less recoil. Competitions in the Netherlands use more accurate and less powerful rifles. These are often much more expensive than the average rifle used for recreational shooting. These rifles use a recoil-reducing mechanism and are often fitted with a bottom or side cocking cock (instead of a break-action barrel).

moc

Powerful broken-barrel rifles are typically sold to people who value power over accuracy. Many recreational shooters choose such a rifle and enjoy the roar that is produced when the pellet reaches the speed of sound. These rifles are often powerful, not too expensive, and popular with younger shooters. These rifles can be used for recreational shooting where cans or larger leaves are shot. However, it is more difficult to achieve great accuracy and precision with one shot from these rifles.

Lower side tensioners and nitron piston

Most shooters who want to practice can have a lot of fun with a spring-loaded rifle. This often applies to slightly more expensive and better models of spring-loaded carabiners, such as those from Weihrauch. Bottom-cocking or side-cocking rifles have a fixed barrel, which by definition makes them slightly cleaner than rifles with a barrel-breaking system. Some spring-loaded rifles are equipped with a gas spring. The rifle is not spring powered, but a kind of gas balloon. The principles of the systems are the same, but the resulting recoil is greatly reduced due to the absence of a spring and piston. In addition, the gas spring does not loosen like a steel spring when it is stretched for a long time. Partly for this reason (and for safety reasons), it is unwise to put down a cocked rifle. Despite all these points, shooting a spring-loaded rifle is quite difficult. If you learn to shoot from the right stance, you will see your striking ability increase significantly.

Co2 cartridge - 12 grams	Co2 cartridge - 88 grams

CO2 and pump action rifles are perfect for recreational shooting in the garden or at shorter distances. These rifles often have a slightly lower muzzle velocity, around 210 m/s with CO2, and up to 245 m/s with pump-action rifles.

Co2 pants

There are certain properties to consider when using Co2 guns. The Co2 cartridge is under an average pressure of 60 bar at 25 degrees Celsius. When it's colder outside, the cylinder pressure may drop. For example, at 12 degrees, the pressure will be about 50 bar. What further affects the pressure of the Co2 cartridge is the cooling that takes place during firing. The Co2 cartridge is strongly cooled by evaporation. Therefore, pellets fired in a row will land a little less hard and lower on the map. After a short wait, the Co2 cartridge will heat up again and you can shoot at full power. This deviation (when firing in rapid succession) can be frustrating for the inexperienced shooter. In medium temperatures, you can shoot a Co2 powered rifle well. Slightly more expensive Co2 rifles, often suitable for 10m competitions, have a regulator installed to maintain an even pressure. The principle of operation of the Co2 rifle is almost the same as that of the PCP rifle.

One of the advantages over PCP rifles is that Co2 rifles are often much cheaper because you don't need a pump or air cylinder. On the other hand, you need Co2 cartridges, which you should buy depending on how much you plan to shoot.

Transmitter

The pump-action rifle was a well-known and well-liked rifle because it had little recoil. The pump-action rifle is a rarity these days after the advent of the air gun. For many owners of such a rifle, it is a legendary model, unfortunately, nowadays the development of pump action weapons is small. This does not mean that the rifle no longer has fans.

The pump-action rifle is equipped with a fixed barrel and can be inflated using the bottom cocking device. The pressure can be measured by how many times you inflate the rifle. In a way, you decide how hard you shoot in the end. This has its advantages if you are dealing with different distances and want to change the bullet's trajectory. The flip side of this system is that it can confuse inexperienced shooters, making it difficult to master the weapon. This leads many people to mistakenly believe that the rifle is unreliable. The rifle also fires one shot per charge. This means that you have to re-inflate the rifle after each shot.

Spring and pump air guns are usually limited to firing single shots due to their mechanism. With each shot, the rifle is cocked and one shot can be loaded into the barrel at a time. Many shooters like this because nodding, reloading, and firing becomes something of a simple pre-shot process. Repeated and systematic reloading of the airgun gives you the peace needed to shoot in concentration.

Placing the pellets

Placing the pellets must be done carefully. Pellets are often made of lead, which makes them soft and easily deformed. In break-barrel rifles, bullets are pressed into the barrel. With sideloaders or bottomloaders, the shot is placed in the barrel, after which the locking mechanism pushes the bullet further into the barrel. The same mechanism closes the barrel. Co2 or air rifles are often equipped with a magazine. Single-shot airguns are loaded with a bottom or side-loading cock, similar to spring-loaded rifles.

Warehouses

Both Co2 rifles and air guns use a multi-round magazine. You preload this magazine and then load it into the rifle in one action. When the magazine is empty, it can be replaced with another magazine. Magazines are often not used in professions.

Pellets and materials

Most bullets or pellets are lead. This type of metal has a number of dangerous properties that you should be aware of. Lead is toxic to humans, so care must be taken when loading and handling bullets to avoid swallowing lead. Lead is also harmful to the environment. It is therefore important that the pellets are collected, for example with a pellet trap, and that no pellets remain on site. Used cartridges can simply be thrown away with the scraps as they are recovered during waste processing. Alternatively, you can use a 2cm thick plywood board, remember that bullets can bounce when firing at a straight board. This should be prevented, for example, by screwing a sheet of lead to plywood. When shooting cards, you can use suitable steel balls, often 14x14 cm. These ball traps collect balls in a container that can be emptied. These ball traps work best when you put a small layer of sand in the bowl. Bullets can then bounce here with less ease.

When shooting loose targets on home turf, it is very important to place the targets in the bullet container. You can also use brass, zinc or copper balls which are slightly less polluting.

Pulled barrel

The trigger pull is done in two parts. First remove the free stroke until you feel resistance. Then you pull the trigger evenly and the shot is fired. We'll talk more about the perfect shot later. We continue the way the pellets pass through the barrel. Most pellets are devil shaped. The rear part of the shot has the shape of a funnel, which, under the influence of high air pressure, is pressed into the spiral grooves inside the barrel. The shot closes the barrel and transfers the rotational movement of the grooves (dimple) and fields (raise) to the projectile. When the pellet leaves the barrel, it rotates around its longitudinal axis, thus maintaining the direction of the barrel on the trajectory of the bullet. For rifles that do not have a rifled barrel, the bullet will tilt immediately after exiting the barrel and deviating from the bullet's ideal trajectory.

Security

Can be used while arming and reloading weapons. For safety, the rifles are equipped with a safety grip. When the airgun is locked, the trigger cannot be pulled. This is based on the assumption that the rifle cannot be fired until the shooter pulls the trigger. Airguns are often equipped with an auto-lock that automatically adjusts the safety when the rifle is cocked. If it doesn't happen automatically, it's important to learn how to lock the rifle when cocked so that it can't be fired until you're ready. This should be done even when the air gun is unlocked and unloaded.

Part of the projectile

When the pellet comes out of the barrel, it flies freely through the air and is subjected to two forces that cause it to deviate from its intended direction. First, the projectile encounters air resistance through which it travels. The bullet slows down due to air resistance. Added to this, of course, is gravity, which pulls the bullet down, so that the bullet begins to fall as soon as it leaves the barrel. A 5.5 mm bullet leaving the barrel at a speed of about 264 m/s drops 5 cm after 25 meters! At 50 meters it grows to over 20 cm. The shooter must correct this deviation using the shooting range or sighting equipment, calibrating it to the bullet's trajectory and distance to the target.

Shooting range and bullets

After hitting the target, the pellet deforms on impact. Earth, wood and special balls hold the pellets after impact. Hard surfaces can crack the pellets, causing pieces to fly. The bullet can also ricochet and continue its journey from a different angle while retaining a lot of energy. If the pellet hits a hard surface at a certain angle, it may ricochet into pieces at right angles that can hit the shooter or bystanders. This already indicates that the shooting range (also on private property) must be properly and safely fenced off, so that no people or animals are in its vicinity.

We recommend that everyone wear safety glasses when shooting. These are glasses designed specifically for shooting. It's very important to shoot at your intended targets and make sure there is shelter behind them for stray bullets. Do not choose hard materials for the backdrop of the shooting range, such as stone or steel.

After purchase and installation, it is necessary to configure the browser. You can also call browser setting zero. The question now is, what is the best distance to place the viewer?

The configuration of the rifle and the distance maintained varies from rifle to rifle and situation, it mainly depends on the situation and the targets being shot. When you shoot cards at 10 meters, as in Olympiacos, it is obvious that you are also setting the spectator at 10 meters. When you aim a bullseye with the crosshair, the bullseye will also hit. If you are shooting targets at different distances, you will notice that where you aim is different from where the bullet will land.

To avoid confusion, we'll first explain some terms. Many terms and concepts related to ballistics and shooting sports come from the English language and therefore cannot be translated well into Dutch.

When you want to hit targets, say 5 to 50 meters, you come across these concepts. Later we will discuss the laws of physics that are important to ballistics. To explain this properly, let's use the example of a rifle. The scope we will be using for this is the AGS 3-9x40 AO Cobalt Mildot. The rifle we use is a Webley Raider 12 PCP with a muzzle velocity of 250 m/s. The sight is placed 3.75 cm above the barrel. We could also use other brands and models for this test.

When starting airgun shooting for the first time, there are a few things to check first:

• Shooters in the backyard? Then make sure there are no people or animals on the shooting range.
• Make sure you hang a large sheet of plywood about 1 meter by 1 meter and at least 20mm thick, make sure pellets cannot leave this place.

After setting the shooting range, you can hang an A4 or A3 sheet. Draw a vertical line about 20 cm long on this sheet and attach this sheet to the center of the target plate.

At a distance of 10 meters from the end of the barrel to the target target, set up a table or bench with a footrest on top. You can easily do it yourself, for example by filling a jute or plastic bag with sand and placing it on a flat surface. Make sure that the height of the barrel is about the same as the height of the target. Sit on a chair or stool and make sure the windbreaker is supported by the rest. Shake and load the rifle. Make sure the rifle is locked and therefore set to safe!

Look freely through the scope of the rifle and look for the point where the image on the lens is optimal. Then aim the gun's crosshair at the target. (Enlarge to maximum, focus with lens and zoom out to 4x magnification). Press the trigger to arm the rifle and shoot the target. Repeat this step twice so that at the end you can see three holes in the sheet of paper that are parallel to the line you drew. Now you can determine the average deviation.

The rifle can now be completely reset via scope settings. Remove the protective caps from the height (lift) and width (spool) (turret) adjustment knobs. The adjustment buttons can be used for horizontal (left/right) and vertical (up/down) adjustments.

Example:

Your average hit group impact is (for example) 8 cm to the right of the line. Now turn the width adjustment knob 10 clicks to the left.

Now shoot the target three more times.

Look again at the average deviation on the vertical line. From the difference between the first and second group of shots, you can calculate how many millimeters represent 1 snap.

You do it as follows:

• First group of shots 8 cm to the right of the vertical line
• 10 clicks to the left
• 2nd group of shots 5 cm from the vertical line

8 - 5 = 3

3: 10 = 0,3

0,3cm = 3mm

With each sound, the viewer jumps 3mm at a 10 meter shot.

Now you can calculate how many clicks a viewer needs to reach the vertical bar.

50 : 3 = 16.67 (round to 17)

You need 17 clicks to get the viewer almost to the vertical line (0.3mm deviation)

Redraw the map and adjust coverage if needed!

You adjust the height of the binoculars in exactly the same way. Take another sheet of paper and draw a horizontal line on it. Redraw the map three times and adjust the range until the bullets hit a horizontal line. If you set the viewer's horizontal and vertical lines separate from each other, you can focus much better on one part of the scene.

You have now reset Range, Rifle and Bullets to 10 meters. Now you can reset the adjustment system to 0 by unscrewing the latch system plate. Now you can reset this image (with the dashes marked on it) to a fixed 0 point. Now you know that the zero point is set at this point. If for some reason you have set your browser differently, you can always restore the original setting!

The crosshair is now correctly set to 10 meters, you can now practice shooting at this distance. You will notice that when shooting at targets that are closer or farther away, the bullets will fly higher or lower. If you intend to shoot at a different distance, you should reset the range again. Even if you fire a heavier or lighter projectile, it will end up lower or higher. The weight of the bullet changes the shot because heavy pellets travel slower, have a shorter trajectory which also has more curvature.

Shooters with little experience will find that the spread of hitpoints around the target is quite large. When you start shooting more accurately you may need to reset the scope again as you now have no deviation. You will also encounter the deviation that arises from the spectator's parallax.

The concept of parallax is quite complex and therefore difficult to explain. Parallax creates an aberration where the object you are aiming at appears to move with the background as you change position. In this section, we will explain how this discrepancy arises.

You can mimic the parallax effect by holding your finger in front of you and looking at it first with your left eye and then with your right eye. The finger does not move, but it seems to move relative to background objects. The same thing happens when you move your eye in front of the lens with the parallax aberration viewer. The scope crosshair moves slightly relative to the object you are aiming at. Below is an example of an aircraft viewer.

You can solve this effect very easily by looking straight through the lens. It is difficult to tell for sure whether the eye is directly in front of the lens. When you look through the lens and see black edges around the image, it may appear skewed through the lens.

High-quality binoculars often have an adjustment with which you can focus on the target. This can be done by adjusting the rear viewfinder lens. These binoculars are designed in such a way that parallax does not occur when the target is in focus and the front lens (Eyepiece) is correctly aligned with the rear lens (Object).

Parallax in focus

The image above shows how a margin of deviation is created around the crosshair when the crosshair is not aligned correctly on the crosshair. This does not mean that the target you are looking at is out of focus. If the eyepiece (first lens) is not adjusted correctly, you can focus the image while there is still parallax deviation because it is not properly adjusted.

Adjusting and focusing the eyepiece is difficult. The best way to do this is to mount the rifle on the mount and then check (by moving your eye back and forth along the lens) for parallax deviation. It is recommended to practice regularly and then at different distances. This gives you a sense of range and allows you to better adjust the parallax for different distances.

Red Dot is a projector where an LED is projected onto a reflective piece of glass or a clear mirror so that a dot or shape is visible. Because the glass is curved, it reflects directly back to the eye. That red dot is ultimately the clue that shows where the bullet should land.

The red dot (hereinafter referred to as RD) is made so that the red-green dot remains aligned with the weapon. This is clearly shown in the diagram below. The great thing about the Red Dot scope is the lack of parallax deflection.

With RD it doesn't matter how you look through the lens because with Red Dot there is usually no magnification so you can still look with both eyes. RD focus is also redundant and it doesn't matter how far the eye is from the lens. The RD is mainly used in situations where quick aiming and shooting is required, such as paintball, hunting, or in situations requiring a tactical sighting device. You can also equip an airgun with RD, they are often less accurate than a scope, but they give you a chance to find your target faster. In addition, RD are also great in an air gun.

RD exists in different versions. The simplest variant is the one with a concave mirror, the more complex version is the RD integrated with the lamp. Tubed RDs are often stronger and more durable than single concave mirror RDs. There are also RDs that are magnified so you can get closer to your goal.

You can make the RD work well in airguns and can be placed out of sight. Since there is no parallax deflection, it doesn't matter if you are looking sideways through the RD. Straight RDs are difficult to adjust at different distances. In addition, in the case of RD, it is often not possible to correct by points, as is possible with a sight equipped with a reticle. As a result, as a marksman looking for accuracy and wanting to hit a target at different ranges, you have less use with RD than with a scope that magnifies the target.

Keep the gun steady

When setting up the airgun, it is important to keep it still. For example, you can sit on a table and rest your rifle on a sandbag or other heavy but soft object. The advantage of this is that the bag absorbs the shock of the rifle and also prevents the rifle from rising when the trigger is pulled. Airguns or Co2-powered rifles can also be loaded in sandbags. By pressing the pocket, you can easily adjust the shot height with minimal movement of the rifle. Later we will discuss and explain the different shooting positions.

For a rifle like the one in the perfectly zeroed example, the sight is as low as possible in the barrel, making the blank quite large. It is only necessary to make adjustments when you get out of there. In practice, you will find that you will only need to make adjustments when shooting at 10 or more than 35 meters. The images below show two examples of fixes. In both cases, as shown in the picture, aim a little higher. As you can see from a distance of 10 meters you need to aim about 0.9 cm higher to hit the target well. At 40 yards you should aim about 1.5 inches higher to get a good shot. The strange thing is that you need to correct relatively more at a short distance than at a longer one. This is often hard to understand because it is counter-intuitive.

For all rifles, bullets or scopes you have an optimal zero position (OZR or Optimum Zero Range), this is the optimal distance to set the zero. In the sections above, we have discussed how to find the best zero position for the rifle you are using. The overall distance and position of the Pointblank is determined by the height of the scope relative to the barrel. Also, binoculars with a larger exit lens are always taller than binoculars with a smaller lens, as shown in the image below. Changing the point gap is done as follows.

Sights were placed on the rifle at different heights.

Low: 30mm - Point blank from 10.7 to 32.1 meters, OZR = 12 meters

Medium: 40mm - Point Blank from 12.1 to 33.2 m, OZR = 15.4 m (example)

Hoog: 50mm - PointBlank van 13,4 do 34,4 m, OZR = 16,6 m

Bullet speed

PointBlank lengthens as speed increases, and PointBlank start and end points change as well.

Using the rifle example where the viewer is 40mm away, PointBlank changes to:

200 m/s: 9,3 do 25,8 metra

230 m/s: 10,6 do 29,3 metra

264 m/s: 12.1 to 33.2 meters (example)

Ball shape (aerodynamic)

Pellets encountering air resistance lose speed faster. This is noticeable at greater distances as PointBlank becomes smaller.

For a beginner, it is prudent to buy a rifle with a reasonable standard muzzle velocity between 220 and 280 meters per second, with the sight placed 30 mm from the barrel. You will be able to shoot very well, especially with a tuned PCP rifle, which is easily accurate at ranges of 10 to 30 meters. These are the perfect distances for people who have little space around the house! If you want to shoot closer or farther, you need to adjust PointBlank. Distance estimation is not easy.

You can specify the distance to your destination in two ways:

Adjustable target

With a scope AO (adjustable viewfinder, lens or field lens), you can adjust the distance by specifying the number of yards by rotating the lens. Unfortunately, this method is often not very accurate. It is best to check and measure all distances from the AO with binoculars. You can then save the actual distances on the binoculars by saving them yourself.

Using the environment

In a familiar environment, you can estimate distance fairly well if you know the distances of other objects in your environment.

Mildot up has an intersection

It is important to know what distance corresponds to the Mildots in your sight. You can measure it and record data about it.

You can easily do this when you know the trajectory of a rifle bullet. We accept the correction of 0.9 cm upwards at a distance of 10 m. Make a sheet with two crosses 0.9 cm apart. Place it at a distance of 10 meters and aim the binoculars at the highest cross (aiming point). The cross at the bottom shows where the point of impact is when the projectile is fired at 10 meters.

In the case of the example rifle, it was slightly less than 1 point below the crosshair. This way you can calculate the point of impact for all distances along the bullet trajectory without having to fire the shot. The image below shows the correction table used by competition shooters as a reference when calculating distances.

Correction card

We will continue to explain ballistic theory in the next chapter.

As discussed in previous chapters, finding the optimal null range is a manual way to learn about a weapon and determine what it is capable of. You can also find out through theory what qualities a rifle has.

We will explain and explore this theory later in this chapter.

Bullet (bullet) trajectory is an important application of physics that has been used many times throughout history. This application was already suitable for the effective use of catapults, bows and arrows, cannons, muskets and ballistic missiles equipped with nuclear warheads. Over time, more and more accurate algorithms have been developed to make the trajectory of this type of projectile as accurate as possible. This is good because it can be applied very well to the trajectory of a rifle bullet.

Calculating dot trajectories is part of the complex field of physics and mathematics. The calculation of the ideal bullet trajectory without taking air resistance into account is often asked in school exams. The shape of a bullet and its behavior when passing through the air depends on so many factors that it is difficult to articulate. As usual in science, the determination of the bullet's trajectory is accompanied by measurements that further explain the bullet's behavior. With the knowledge gained throughout history, software has been created that can accurately simulate the trajectories of a ball. Well-known manufacturers of binoculars and other optics, such as Hawke Optics, have designed beautiful ballistic software. The programs are available in different versions for desktop and smartphone applications.

This program 4.3.5. (see above) is offered free of charge by Hawke Optics. You can download this program atwww.hawkeoptics.com. The show is pre-programmed for familiar Hawke viewers. This software is regularly updated and the smartphone variants are also easy to use.

To determine the trajectory of a dot, a series of data is needed:

• Your rifle's muzzle velocity in meters per second (m/s) or muzzle energy in joules
• Bullet caliber and weight
• Ballistic coefficient (BC value) of shot and shape coefficient (G1 to G7, GS, GA, etc.)
• The height of the sight above the barrel.

Speed ​​and energy

The velocity (at the barrel) is the velocity (wvelocity) of the projectile exiting the barrel. As the bullet leaves the barrel, it begins to slow down and is pulled down by gravity. Velocity is expressed in meters per second (m/s). You also often see English measurements in movies and other velocity and gun data expressed in feet per second (ft/s), because the idea of ​​1 meter per second equals 3.28 feet per second (1 m/s = 3.28 ft/micro).

Energy (stomach) (E) has already been discussed. You can calculate the energy of your rifle using the following formula:E = ½ m v².Let's take, for example, a velocity of 264 m/s for a pellet with a mass of m = 0.959 grams.

E = ½ x 0,000959 kg x 264² m/s

E= 33,4 dzula

The (oral) energy is often difficult to determine from data provided by suppliers or is unrealistic. For example, velocities are determined with extremely light projectiles, making them very high. When suppliers specify in specific joules, this is often a good guideline rather than a specific amount. The performance of the rifle depends on the type of bullet used. This may change as pellets of a different weight are used. Speed ​​and energy differences always exist, even with rifles of the same make and type.

Chronograf

The easiest, fastest, and most accurate way to measure rifle speed is with a stopwatch. The cheapest models are offered from €68, such as the Acetech AC5000. Chrono apps such as "Chrono Connect Mobile" are now also available. This app measures the speed of your rifle using your phone's microphone to record the sound of the shot and its effect on the target. The application measures the time it takes the bullet to reach the target and calculates the speed of the rifle based on this. To get the most accurate result, it is important to correctly enter the distance between the tip of the barrel and the target, the weight of the projectile and the BC value into the program. It is also important that the shooting target is made of a material that makes a loud noise when hit.

Weight and caliber

Bullet weight and caliber are listed in the box it comes in. If this is not the case, the scale can often be found on the respective brand's website.

Form factor and BC value (G1 to G7, GS and GS)

The BC value determines the aerodynamic value of the object. Any object that moves through the air is resisted. This resistance is expressed in the magnitude of the force (F) that friction exerts on a moving object. The drag coefficient (Cw) depends, among other things, on the shape of the object and the structure of the surface. The ballistic coefficient does not express the resistance an object encounters, but rather the force of penetration. This means that high air resistance results in a low BC value. The BC value of pellets can generally be obtained from or between pellet suppliers. ONhttp://www.chronoconnect.com/pellet-list.htmlthere is a list that already shows many BC values ​​and weights.

The shape factor is a kind of filter added to the BC value. The typical G1 aspect ratio is more common with the average dot. As you can clearly see in the image, the G7 represents a different shape. This projectile behaves differently during its trajectory. The GA form factor was developed for devil-shaped balls. If this is not available in the software you are using, you can also use G1.

Projection and placement height

You can measure the diopter height relative to the barrel. You can do this by measuring the barrel diameter (A), the barrel diameter (C) and the distance between the barrel and barrel (B). (see picture)

Your viewer height is then:

Height = ½ A + B + ½ C

An example is the AGS 3-9x40 AO Cobalt Mildot with a height of 3.75 cm.

The laser effect in a gun is familiar to everyone (we all watch movies). Lasers are cheap and look nice on an airgun. In addition, it is of course very easy to use.

With lasers, you can easily check your parallax. If you set the laser at a fixed distance to a point where the laser is clearly visible in the scope, you can easily see how much parallax deviation occurs when aiming at a target at a different distance. You can check this by moving your eye back and forth in front of the eyepiece, if the laser is moving, the parallax is not set correctly.

You can also fix the laser aiming point when it goes beyond the empty point. If we take the example from our rifle, the void point is approximately 12.1 and 33.2 meters apart.

If you want to shoot even more accurately, for example with a 0.5 kill zone (previous calculations used a 1cm kill zone). OZR moves to 17 yards which makes the void point much shorter. The void point is at this point from 14.7 to 29.6 meters. At this distance, the point of impact of the shot is no further than 2.5 mm from the aiming point. If you want to hit something closer than 14.7 meters, you have to correct something, you can do that with a laser.

After mounting the laser on the rifle, you can create a second hollow point. As shown in the picture below. The red line (diagonal) is the line of the laser beam starting 0.5 cm above the barrel and ending at 13 meters. From 5 meters the line extends until it intersects the red line of the crosshair at 0.25 meters from the trajectory of the ball. When aiming at short distances, your laser will be within a 0.5cm kill zone.

Use the handle at a 45-degree angle to position the laser so that it is not in front of the viewer. The optimal height for the laser is 0.5 cm and this height can be achieved by placing it as close to the barrel as possible.

You practically only use the laser as a reference point to establish your aiming point. So it is not a problem that the laser is tilted in the barrel. You will always aim at the target with the scope finder. We use the laser to correct and turn it on completely when aiming at the target.

The tip of the laser is visible to the viewer. If the dot remains below the horizontal line of the cross, it indicates the height of the point of impact of the projectile. You can see as shown in the image that the laser hits two points below the cross. You can remember this fix after which you turn the laser off again. Then aim at the point of the second line under the crosshair.

If the laser is more than 15 meters above the crosshair, the crosshair is your target. Then you are in the viewer's field of view, which extends to 29.6 meters. This strike allows you to shoot in the zone of 0.5 cm with little effort from 5 to 29.6 meters. As indicated, a laser can go a long way in this way to clean up air gun shooting.
