The speed at which a bullet becomes unstable and can no longer be accurately fired from a gun largely depends on the type, caliber, and design of the bullet. Generally speaking, depending on the size and weight of the bullet, it will begin to become unstable and become unsuitable for shooting beyond about 800-900 meters per second.
As the bullet continues to speed up, the aerodynamic forces acting on the bullet will cause its trajectory to become progressively more unpredictable and it would no longer be accurate at distance beyond several hundred meters.
This can be particularly true with certain designs, such as those with a truncated or boat tail rear. Also, bullets with a high degree of copper-plating surrounding the core can degrade more quickly when they come close to Mach One velocities.

What is the range of bullet stability?
Bullet stability is a measure of how accurate and consistent your shots will be and how well your bullet will fly through varying air density and wind. The range of bullet stability can vary between different calibers and bullet types.
Generally speaking, bullet stability is affected by a few key factors such as weight, velocity, drag, and twist rate. A higher bullet weight will generally lead to higher levels of stability, as it reduces the amount of drag that the bullet experiences when it passes through the air.
Similarly, higher velocities will cause the bullet to remain in the air for longer and become more stable. High drag bullets tend to become unstable more quickly and will travel shorter distances before beginning to tumble.
Twist rate, or how quickly the rotational rate of the bullet decreases while in flight, also affects bullet stability. For example, a high twist rate helps a bullet remain stable enough to travel longer distances with more accuracy, while a low twist rate causes a bullet to become unstable quickly, reducing its accuracy and range.
To determine the range of bullet stability, you will need to compare the bullet’s weight, velocity, drag, and twist rate to see how well it performs in different environmental conditions and ranges.
What is gyroscopic stability of a bullet?
Gyroscopic stability of a bullet is a phenomenon in which the bullet maintains its orientation while in flight due to its rapid rotation. This stability is achieved through a combination of the spin of the bullet, the forward speed of the bullet and the air resistance experienced by the bullet.
The rapid spin of the bullet creates a gyroscopic effect, providing an inertial stability that helps the bullet to travel straight. This gyroscopic effect helps to counter the destabilizing effects of air resistance and wind drift.
In addition, the spin helps to stabilize the bullet, as the bullet’s nose is always pointed in the same direction as its direction of travel, which helps maintain accuracy and stability in flight. Gyroscopic stability is especially important for small caliber bullets, as the spin and stabilizing effects of the gyroscopic force helps to counteract the destabilizing effects of wind, making them more accurate and reliable in flight.
Can a bullet be over stabilized?
Yes, a bullet can be over stabilized. This means that the bullet was not able to properly spin in the barrel and is not well balanced, which causes it to fly erratically and inaccurately when shot. This can happen when a bullet is too long for the barrel, when it is seated too deeply in the case, or when the bullet nose is too large or too heavy.
It can also happen if the gun is not properly lubricated or if its rifling is not in good condition. Over stabilized bullets usually produce erratic or inaccurate flight patterns, poor accuracy, or recoil problems.
If over stabilization is a problem, the best solution is to make sure that the bullet is properly balanced and seated, use the correct type and amount of lubricant, and make sure that the rifling is in good condition.
Can you spin a bullet too fast?
Yes, it is possible to spin a bullet too fast. When a bullet is fired from a gun, some spin is imparted on the projectile by grooves in the barrel known as rifling. The more spin imparted upon the bullet, the more accurate and consistent the bullet’s path will be, allowing for greater precision and accuracy when shooting.
However, if the bullet is spun too fast, it can cause issues like destabilization, inaccuracy, and even premature detonation which can be a serious safety hazard. Generally speaking, bullets spin at rates of up to 28,000 revolutions per minute, so spinning at higher speeds is not recommended unless you are a trained professional who knows the risks and how to manage them properly.
How does gyroscopic stability work?
Gyroscopic stability is a concept that describes how an object with a spinning mass (e. g. a wheel, propeller, or flywheel) uses angular momentum to resist a force that would otherwise destabilize it.
It works by harnessing the force of inertia and centripetal force to create a stabilizing effect. This stability is what allows for a bicycle to stand upright, a propeller to spin and stay in position, or a helicopter to inhibit any unwanted movements in the air.
In terms of how it works, gyroscopic stability occurs due to a mechanical gyroscope. This gyroscope consists of a flywheel that is mounted inside three gimbals. The flywheel is made out of a heavy material that is able to rotate quickly, such as metal.
The gimbals are attached to the outside of the flywheel and are free to rotate in any direction. In order for stability to be achieved, the flywheel must be able to spin rapidly and the gimbals must be securely attached to the flywheel.
To understand how gyroscopic stability is achieved, one must consider the concept of angular momentum. Angular momentum is generated when a spinning mass experiences an external force, such as a gust of wind or centrifugal force, wherein the flywheel attempts to rotate towards the direction of the force, while the gimbals keep the flywheel in the same orientation while it spins around its axis, causing it to remain upright.
This creates a stabilizing effect and prevents untimely and undesired changes in direction or orientation.
In summary, gyroscopic stability is achieved by the use of a mechanical gyroscope that consists of a flywheel and three gimbals. The gyroscope makes use of the concept of angular momentum to create a stabilizing effect.
This prevents any sudden movements and allows things such as propellers and helicopters to stay upright and in the same direction or orientation.
Can a speeding bullet produce a sonic boom?
Yes, a speeding bullet can produce a sonic boom. Sonic booms occur when a supersonic object—traveling faster than the speed of sound—moves through the air. The energy wave created by the projectile of a bullet moves faster than sound, resulting in a sonic boom that sounds like a loud explosion.
Reports indicate that the boom created by a bullet will last for just a few milliseconds. Most sonic booms are too short and too low in intensity to actually be heard by the human ear, but they can be detected and measured with specialized equipment.
Can you dodge a bullet from sound?
No, it is impossible to dodge a bullet from sound. The sound of a bullet traveling through the air is too quick and too quiet to identify and react to in enough time to dodge it. Even if the sound of a gunshot is heard, the bullet itself has already been fired and is travelling at an incredibly high speed, making it impossible to move out of its path.
Additionally, the sound of a gunshot can be muffled or distorted by intervening objects such as walls or structures. Therefore, trying to dodge a bullet based solely on the sound of a gunshot is not only impossible, but also risky and unsafe given the variable nature of sound and the speed of a bullet.
Can a supersonic bullet be silenced?
In short, the answer is no. When a bullet is fired, it creates a loud bang due to the rapidly expanding gases created by the burning propellant. The piercing noise you hear is not actually the bullet itself breaking the sound barrier, but rather these expanding gases.
To silence a bullet, the gases would have to be contained, which would require some form of sound suppression technology. Such a system would require the bullet to pass through a device that absorbs the expanding gases from the bullet, thereby silencing the bullet.
Unfortunately, the materials required for such an system would be very heavy and bulky and would greatly increase the load of the firearm. In addition, it would be extremely difficult to design a device that could contain the high pressure and temperatures of a supersonic bullet, meaning a silenced supersonic bullet is not currently possible.
What bullets are supersonic?
Most commonly created by high powered rifles or handguns. Examples of supersonic bullets include. 223 Remington,. 308 Winchester, and. 30-06 Springfield. These are all cartridge based firearms, which provide enough power to send the bullet faster than the speed of sound.
Additionally, handgun cartridges such as the 9mm and. 45 ACP can also fire supersonic bullets when loaded into a higher power handgun such as a handgun chambered in 10mm. Some of these bullets can reach speeds of upwards of 1,400-2,000 feet per second.
How fast is a 9mm bullet in mph?
The velocity of a 9mm bullet varies depending on the type of ammunition being used, as well as other factors such as barrel length and the rifling of the barrel. Generally, the average speed of a 9mm Luger round (the most common type of 9mm ammo) is around 1,150 feet per second (fps), or around 770 miles per hour (mph).
Additionally, some types of 9mm ammo can reach velocities as high as 1,700 fps or 1,134 mph.
Will a gun fire in space?
In theory, a gun could fire in space. However, in practice, it would be an ineffective weapon due to a lack of oxygen. In order to fire a gun, the chemical reaction of the gunpowder requires oxygen. Without oxygen, there will be no combustion, and therefore, no bullet will be fired.
This means that a gun can theoretically fire in space, but without oxygen, there will be no combustion, and the gun will be unable to fire. Thus, while a gun may be able to fire in space, it is unlikely that it would be an effective weapon.
What happens if a bullet hits bone?
When a bullet hits bone, the outcome depends on several different factors such as the caliber and size of the bullet, as well as the bone’s resistance and strength. Generally, the larger and denser the bone, the more likely it is to stop or deflect the bullet.
On the other hand, smaller and softer bones may allow the bullet to pass through. When a bullet strikes bone, it often breaks it into pieces and can cause a laceration that can be very serious and require medical attention.
The amount of damage caused will also depend on the velocity of the bullet, angle of impact, and type of bullet (jacketed or non-jacketed). The amount of tissue damage may also vary depending on the location of the impact.
For example, if a bullet were to hit the shoulder blade it may break into smaller pieces and cause severe tissue damage, while a bullet passing through the softer parts of the body such as the stomach or thigh may generally cause less tissue damage.
In summary, the outcome of a bullet hitting bone will depend on the size of the bone, impact angle, and velocity of the bullet. Depending on the circumstances, it can cause sever tissue damage and lacerations, so it is important to seek medical attention if needed.
What does an AK-47 bullet do to a body?
An AK-47 bullet can cause a variety of damages to the body, depending on the area it impacts. Generally speaking, the damage is most often severe and can be life-threatening. The bullet’s velocity and kinetic energy can seriously damage tissue and organs, and has been known to cause internal bleeding, broken bones and lacerations.
The bullet can pass through multiple organs and cause catastrophic damage, which can be fatal if not treated quickly. It can cause bones to shatter, tear through flesh and produce cavitation (cratering) in the tissue.
In a worst-case scenario, the bullet can cause an individual to suffer an almost immediate death due to an acute disruption of the cardiovascular system, brain hemorrhage and/or a transection of any vital organ.
Therefore, it is important for medical personnel to be aware of the types of injuries associated with an AK-47 bullet and to act quickly to treat them in order to prevent further deterioration or death.
