Flight range of a Kalashnikov assault rifle bullet 5.45×39: what drivers and hunters need to know

Modified Kalashnikov assault rifle AK-74 with cartridge caliber 5.45×39 mm - one of the most common small arms in the world. Its technical characteristics, including bullet range, are of interest not only to military personnel and hunters, but also to ordinary car enthusiasts. Why? Because understanding ballistics helps you assess the risks when shooting near roads, on shooting ranges or in hunting areas where vehicles may be present.

In this article we will figure out how far a bullet flies from AK-74, how weather conditions, the type of cartridge and the angle of the shot affect its trajectory. You'll also learn why this data is important for drivers traveling in remote areas that include shooting ranges or military training areas. The information will be no less useful for those who plan to purchase civilian weapons for this caliber - for example, a carbine Saiga-5.45.

Technical characteristics of the 5.45×39 mm cartridge

Cartridge 5.45×39 mm was developed in the USSR in the 1970s as a response to the American program SPIW (Special Purpose Individual Weapon). Its key difference from its predecessor - the cartridge 7.62×39 mm - smaller caliber and higher muzzle velocity. This made it possible to improve the accuracy of fire and reduce recoil.

Main parameters of the cartridge:

• 🔹 Caliber: 5.45 mm
• 🔹 Sleeve length: 39 mm
• 🔹 Bullet weight: 3.4–3.6 g (depending on type)
• 🔹 Initial speed: 880–900 m/s (from a 415 mm long barrel)
• 🔹 Bullet energy: ~1300–1400 J

Modern modifications of the cartridge, such as 7N6 (steel core) or 7N10 (with enhanced penetrating action) have slightly different characteristics. For example, 7N10 develops initial speed up to 920 m/s, which increases the range of effective destruction.

Maximum and effective firing range of the AK-74

Bullet range and effective firing range are two different concepts. Maximum range determined by the ballistic properties of the cartridge and can reach 3–3.5 km under ideal conditions (elevation angle 30–35°, no wind). However, at such a distance the bullet loses almost all kinetic energy and does not pose a danger.

Effective range is the distance at which a bullet retains enough energy to hit a target. For AK-74 it amounts to:

• 🎯 Sighting range: 1000 m (with standard sight)
• 🎯 Direct shot range at the chest: ~440 m
• 🎯 Lethal range: up to 1350 m (in manpower)

When shooting at distances over 600 m, the trajectory of the bullet becomes highly parabolic, which requires significant adjustment of the sight. For example, at 1000 m the bullet falls on ~5 meters below the aiming line, if you do not take into account the amendment.

Factors affecting the range of a bullet

The actual range of a bullet depends on many factors, which can be divided into three groups: constructive (related to weapons and cartridges), external (weather conditions) and human (shooter skills). Let's take a closer look at them.

1. Design factors:

• 🔧 Barrel length. Shortened versions (for example, AKS-74U with a 200 mm barrel) lose up to 20% of the initial bullet velocity, which reduces the range by 30–40%.
• 🔧 Bullet type. Jacket bullets (eg. 7N6) fly further than expansive ones (for example, hunting 5.45x39mm soft core).
• 🔧 Condition of the trunk. Bore wear increases dispersion and reduces muzzle velocity.

2. External factors:

• 🌬️ Wind. A side wind with a speed of 5 m/s carries a bullet 1000 m to ~1.5 meters. A tailwind or headwind affects the range (increases or decreases it by 10–15%).
• 🌡️ Temperature and humidity. In cold air (-20°C), the density is higher, which reduces the range by 5–7%. High humidity also slows down the bullet.
• 🏔️ Altitude above sea level. In the mountains (at an altitude of 2000 m) the air is thinner, and the bullet flies 10–12% further.

3. Human factors:

• 🎯 Elevation angle. The optimal angle for maximum range is 30–35°. When firing at an angle of 45°, the range decreases due to increased air resistance.
• 🤲 Shooting technique. Incorrect positioning or jerking of the trigger increases dispersion, which is critical at long distances.

How to calculate wind correction?

To roughly calculate the wind drift of a bullet, use the rule: “Wind speed (m/s) × Range (hundreds of meters) × 0.15 = Drift in meters.” For example, with a wind of 4 m/s and a distance of 500 m, the drift will be ~3 meters (4 × 5 × 0.15).

Comparison with other calibers: what flies further?

For clarity, let’s compare the bullet’s flight range 5.45×39 mm with other popular cartridges used in machine guns and rifles. The data is given for standard military modifications of weapons with a barrel length of 400–500 mm.

Cartridge	Initial speed (m/s)	Max. range (m)	Effective range (m)	Examples of weapons
5.45×39 mm (7N6)	900	3100–3500	1000–1350	AK-74, AK-12, Saiga-5.45
7.62×39 mm (PS)	715	2700–3000	800–1000	AKM, SKS, Vepr-Okhotnik
5.56x45mm NATO (SS109)	930	3600–4000	1200–1500	M16, AR-15, G36
7.62x51mm NATO (M80)	830	5000–5500	1800–2000	M14, FN SCAR-H, SVD

As can be seen from the table, the cartridge 5.45×39 mm inferior in maximum range 7.62x51mm NATO, but superior 7.62×39 mm (used in AKM). At the same time 5.56x45mm NATO has similar characteristics, but benefits slightly due to the more aerodynamic shape of the bullet.

Interesting fact: despite the smaller caliber, 5.45×39 mm at distances up to 600 m exceeds 7.62×39 mm in terms of penetration ability due to higher speed and steel core. This makes it popular among medium game hunters (such as wild boar or deer) in regions where the use of rifles chambered for this cartridge is legal.

Road safety: what do drivers need to know?

For motorists traveling to remote areas or hunting grounds, knowledge of ballistics 5.45×39 mm may be critical. Here are some practical tips:

⚠️ Attention! If you see a "Shooting Range" or "Military Range" warning sign, do not ignore it. Even at a distance of 2–3 km from the shooter, a bullet can ricochet off hard surfaces (stones, asphalt) and pose a danger to vehicles.

What to do if you find yourself in a shooting zone:

If you are planning to hunt using a rifle chambered for 5.45×39 mm, consider:

• 🚗 Transportation of weapons. In Russia, transportation of weapons and ammunition in a car is permitted only in an unloaded state, in a case and separately from ammunition. Violation of the rules threatens with a fine of up to 5,000 rubles (Article 20.8 of the Code of Administrative Offenses of the Russian Federation).
• 🎯 Choosing a shooting location. You can shoot only in specially designated areas (hunting grounds) at a distance of at least 300 m from roads and residential buildings.
• 🛡️ Car protection. If you park near a shooting site, avoid placing your vehicle in a line of possible ricochet (for example, near rocks or metal structures).

Particular attention should be paid penetration ability bullets 5.45×39 mm. At a distance of up to 300 m, it penetrates a standard automotive sheet of metal 1–1.5 mm thick, and at 100 m it even penetrates class 2 body armor. This means that an accidental shot into the road could cause serious damage to the vehicle or its occupants.

Myths and reality: debunking popular misconceptions

Around the cartridge 5.45×39 mm and machine gun AK-74 There are many myths circulating. Let's look at the most common ones and compare them with real data.

Myth 1: “A 5.45 mm bullet is not dangerous at a distance of over 1 km.”

❌ Reality: Although the kinetic energy of a bullet at 1000 m is reduced to ~200 J (for comparison, a 9x19 mm pistol cartridge has an energy of ~500 J), it is still capable of causing severe wounds if it hits unprotected parts of the body. In addition, ricochet from hard surfaces can make the trajectory unpredictable.

Myth 2: “The AK-74 shoots further than the AKM due to its smaller caliber.”

❌ Reality: Maximum range 5.45×39 mm really more than 7.62×39 mm, but the difference is only ~20–25%. Main advantage 5.45 mm - in a flatter trajectory at distances up to 600 m, which makes aiming easier.

Myth 3: “A 5.45 mm bullet does not penetrate body armor.”

❌ Reality: Standard bullet 7N6 penetrates body armor of class 1–2 protection (according to GOST R 50744-95) at a distance of up to 200–300 m. To protect against it, armor of class 3 and higher is required (Kevlar + ceramic plates).

Myth 4: “For hunting, 5.45x39 mm is less effective than 7.62x39 mm.”

❌ Reality: On the contrary, thanks to the higher speed and steel core, 5.45 mm provides the best stopping effect on medium game (up to 100 kg). However, for large animals (elk, bear) it is less preferable due to its smaller caliber.

Practical Application: Where is 5.45x39mm used today?

Despite the fact that the cartridge 5.45×39 mm was developed for military needs, today it is widely used in the civilian sphere. Let's look at the main areas of use:

1. Military affairs:

• 🪖 Army machine guns. AK-74, AK-12, AK-15 (modification for 5.45 mm) are in service in Russia and the CIS countries.
• 🎯 Sniper rifles. For example, SV-98 or VSSK "Vympel" (chambered 5.45×39 mm with a heavy bullet).

2. Hunting and sport:

• 🦌 Hunting rifles. Saiga-5.45, Vepr-5.45 and other models are permitted for civil circulation in Russia. They are used for hunting wild boar, deer, and roe deer.
• 🏆 Practical shooting. The cartridge is popular in the discipline IPSC (in the "Standard Manual" class).

3. Self-defense (limited):

• 🛡️ Carbines for self-defense. In some regions of Russia, it is allowed to store and carry shortened carbines under 5.45×39 mm for protection from wild animals (for example, in Siberia or the Far East).

For motorists who hunt or shoot, it is important to remember legal nuances:

• 📜 Weapons permit. To purchase a carbine for 5.45×39 mm A hunting license and permission from the Russian National Guard are required.
• 🚔 Transportation. The weapon must be transported in a case, unloaded, with separately packaged cartridges (no more than 400 pieces without special permission).
• 🎯 Use. Shooting is permitted only in designated areas. For violation - a fine of up to 50,000 rubles or deprivation of the right to own weapons (Article 20.13 of the Code of Administrative Offenses of the Russian Federation).

⚠️ Attention! If you carry a weapon in a car, never leave it unattended, even at a gas station. Theft of a car with a weapon on board is equivalent to its loss and entails criminal liability (Article 224 of the Criminal Code of the Russian Federation).

FAQ: Frequently asked questions about the range of the AK-74 bullet

❓ What is the maximum distance a bullet from an AK-74 can fly?

Theoretical maximum bullet range 5.45×39 mm amounts to 3100–3500 meters at an elevation angle of 30–35°. However, at such a distance the bullet loses almost all its energy and poses no danger. The real threat remains at a distance of up to 1500–1800 m, where a bullet is still capable of penetrating thin metal or glass.

❓ Can a 5.45 mm bullet penetrate a car?

Yes, at a distance of up to 300–400 m, a standard bullet 7N6 pierces the door or hood of a passenger car (metal thickness 0.8–1.2 mm). It does not penetrate armored glass (multi-layer), but can damage a regular windshield. At a distance of over 600 m, the probability of penetration decreases, but the ricochet remains dangerous.

❓ How does wind affect the firing range of an AK-74?

A side wind blows the bullet to the side, and a head or tail wind changes the range. For example, with a wind of 10 m/s:

• 🌬️ Side wind: drift per 1000 m - ~3 meters.
• 🌬️ Headwind: reduces range by ~10%.
• 🌬️ Tailwind: increases range by ~8–10%.

To compensate for drift, experienced shooters use sight correction or “downwind” lead.

❓ Is it allowed to hunt with a 5.45×39 mm carbine in Russia?

Yes, but with reservations:

• 📜 Necessary hunting license and permission to store and carry weapons.
• 🦌 Hunting is allowed ungulates (boar, deer, roe deer) and some predators (wolf, lynx).
• 🚫 Hunting is prohibited fur animals (fox, hare) and birds - this requires shotguns.

Important: in some regions (for example, in the Moscow region) hunting with rifled weapons is prohibited due to high population density.

❓ What is the difference in range between AK-74 and AK-12?

Both machine guns use a cartridge 5.45×39 mm, therefore maximum range they have the same (~3100–3500 m). However AK-12 has:

• 🔫 More ergonomic stock and pistol grip, which improves shooting accuracy.
• 🎯 Modern sight (for example, 1P87), allowing you to shoot more efficiently at distances up to 800 m.
• 🔧 Improved recoil due to the muzzle brake-compensator, which increases accuracy during automatic shooting.

As a result AK-12 shows better accuracy at ranges over 500 m, but maximum range remains the same.
