How Fast does a Bullet Travel – Amazing Facts About Bullet Speed

How Fast does a Bullet Travel

Guns are really just deadly objects but they have been part of human’s life since centuries, and actually it has become a great source of self-defense for the whole world. According to the history and evidence first gun was found in China around AD 1000, and that’s actually more than 1019 years. Since then humans did have done a great effort to make more weapons for defense with new features and developments.

If you have ever seen a bullet shot from gun in real life or either in movies, then you have already know that you can’t see it with a naked eye because a bullet travels really fast like real fast.

The speed of a bullet depends upon the type of gun or a shotgun used for shooting as well as quality of the ammo, feel free to check out 223 ammunition here.. There are so many factors that matters in the speed of a bullet like how fast does a bullet travel, such as weight, material used, power of the explosion, dimension, etc.

If we talk about average so an average bullet travels at around 2736 Kilometers/hour or 1700 miles/hour.

How Bullets Travel?

Now let’s talk about how bullets travel or how do bullets travel fast. The barrel of the revolver has spiral grooves, so the bullet can spin very rapidly. The spinning ball is like a gyroscope: The spinning ball looks almost similar to the gyroscope: a “stubborn” wheel-like spinning constantly in the same way. The gyroscope tries to withstand any force applied while rotating.

When you let go of it, it will quickly tilt to the other side. Therefore, it is difficult to mislead them when things change. We call this idea inertia or gyro stability. The bullets behave in the same way: when spinning, the bullets move in the air in a more direct way, making it more difficult to distract the target and increase the chance of hitting the target.

We think that bullets fly in a perfect straight line, and how fast do bullets travel but this is not the case. When the ball moves in the air, various forces will act on it. In a very short stretch, the ball more or less follows a straight line. At a certain distance, they move in a small downward bending motion because gravity pulls them towards the ground as they move.

The air resistance, rotation and rotation of the projectile also complicate the situation. When all these factors—the movement of the bullet, gravity, air resistance, recoil, and rotation—are added together, the bullet will follow a very complicated corkscrew path as it travels through the air.

Conventional Guns

In conventional weapons, the muzzle speed depends on the amount of powder, the quality of the powder (related to the speed of chemical combustion and expansion), the quality of the projectile and the length of the barrel. Slowly burning powder requires a longer barrel. On the contrary, to finish burning before leaving, heavier projectiles can be used. It is a mathematical compensation.

When using the same amount of propellant, the faster burning propellant can push the lighter projectile at a higher speed. Inside the weapon, the air pressure generated by the combustion process is the limiting factor for the projectile speed. Therefore, the quality and quantity of propellant, projectile weight and barrel length must be balanced to achieve safety and optimize performance. A longer barrel gives the throwing ability more time to handle the bullet range.

Thereby, under all other conditions being equal, a longer barrel usually provides faster speed. However, as the ball moves through the hole, the pressure of the subsequent powdered gas will decrease. The ball and barrel and resistance will counteract the air pressure behind it, and from then on, the speed of the ball will decrease.


The inside of the barrel has a spiral corner, which makes the ball rotate and keep the ball stable in flight, just like throwing into a spiral football, the ball is straight and stable. This mechanism is called slotting. The bullet is more likely to spin before it leaves the gun. Therefore, a longer barrel can improve the overall accuracy of the weapon.

If you examine the shooting group of a paper target consisting of a 2-inch (51 mm) barrel, a 4-inch (100 mm) barrel, and a 6-inch (150 mm) barrel, you can see that the longer barrel produces a tighter “bundle”. When, which ball is closer to the target. The ball passing through the barrel is pushed forward by the expanding gas behind it. This gas is generated when the trigger is pulled, so that the hammer hits the primer, which ignites the solid propellant in the cartridge and ignites the solid propellant in the cartridge. Misfires because of defective reloading primers are quite rare, but they do happen sometimes.

Leaving the barrel, the expanding gas burner stops pushing the ball. When firing from a 51mm pistol, the bullet only needs to rotate the 51mm track before leaving the barrel. -Inches (51mm) of acceleration space, and then you can fly backward without additional force.

In some cases, the powder in the short-barreled cannon may not be completely burned, so the muzzle velocity of the 51mm cannon will be slower than the muzzle velocity of the 100mm cannon, which is smaller than the 6-inch (150mm) canno-pistol. The aspect ratio of large naval guns is high, ranging from 38:1 to 50:1. This feature ratio can exploit the weapon projectile velocity.

When using electric rail cannons to modernize naval weapons, electromagnetic cannons fire projectiles with electromagnetic pulses. These electromagnetic guns overcome the above limitations. The initial velocity of the bullet increases. Another major advantage of railguns is that they do not require explosives.


As a result, ships do not need to transport fuel, and ground stations do not need to maintain fuel stocks. Explosive fuels stored in large quantities can be explosive. Although this situation can be mitigated by preventive measures, railguns usually avoid such preventive measures. Due to the already high speed, the internal charge of the projectile can also be eliminated. This means that projectiles become strictly powered weapons.
