This spiraling is called rifling.
This imparts a stabilizing spin to a projectile. The M16 has a very tight spiral, but the bullet shouldn't tumble until it hits a target.
If you picture a bullet, when the narrow tip first hits a target, it will cause the rest of the bullet to tumble, end over end, and often fragment as well.
What else can I help you with?
Was the spiraling barrel in an m-16 rifle designed to cause the bullet to wobble?
No. Rifling is intended to stabilize the projectile.
What causes a bullet to spin when fired?
Rifling in the barrel is actually grooves cut into the barrel by the manufacturer to cause the bullet to spin as it leaves the barrel. Before rifling the bullets would tend to tumble when they left the barrel causing them to have shorter range and be less accurate.
Will a shorter barrel cause mid flight bullet tumble at 4 to 6 hundred yards in the 5.56 NATO?
Yes,they can,and do tumble when fired from shorter carbine barrels. And at closer ranges than say,a coupld hundred yards.I know because I fired such a round about forty five minutes ago.
What part makes bullet spin on hand gun?
The rifling in the barrel. These are grooves cut on the interior of the barrel that twist around and cause the bullet to spin as it passes down the barrel. The spin stabilizes the bullet and promotes accuracy.
When does a bullet start to tumble?
Round accuracy is improved by spinning the projectile. This is achieved by spiral grooves running down the length of the barrel.This spin strengthens the momentum of the bullet along its trajectory and in part creating a stable vortex around the projectile.Along its flight air friction slows and weakens the stable momentum of the projectile. Random environmental factors such as wind, particles, varying air pressure, then act on the bullet sending it off course.Yet the weapon itself can be a cause of tumble also. Uneven cartridge and wear of the barrel allow the explosive forces and gasses to cause tumbling. That's why you can strip a weapon and change the barrel.So in most respects the bullet begins to tumble as soon as it exits the barrel. A good indicator of when the tumble effects accuracy is the 'effective range' of a caliber. This a combination of unacceptable accuracy and ineffectual damage to a target. IE beyond the maximum range you can get hit and have nothing more than a minor bruise.
Why does a bullet rotate?
A bullet rotates in flight due to the rifling inside the barrel of a gun. The rifling creates grooves that grip the bullet and cause it to spin as it travels down the barrel. This spin stabilizes the bullet's trajectory and improves accuracy.
What would cause a bullet to explode after it leaves a rifle barrel?
how fast it is going
Why were the new rifles preferadble to muskets?
Rifling - small spiral grooves in the barrel of the gun - cause the bullet to spin, and become gyroscopic stabilized. Smoothbore (musket or shotgun-style) barrels don't spin the bullet, and so it can tumble erratically. This causes the bullet to move off of its intended path, and will increase wind resistance. So rifles are preferable to muskets because they are more accurate, and shoot farther.
How are bullet striations created?
Where a bullet is pushed through the barrel of a rifled firearm, spiralgrooves cut into the inside of the barrel (rifling) cause the bullet to spin. This provides for better accuracy- and at the same time, makes marks (striations) on the bullet. A shotgun does not have those grooves, and does not produce striations on the projectile.
What makes a bullet spin?
The barrel of the gun has lands and grooves (grooves and ridges) cut in a spiral. The bullet molds to these and starts to spin as it moves down the barrel. The bullet just continues to spin after it leaves the barrel.Correct. The ridges are known as 'lands'. It is possible to calculate how fast a bullet will spin if you know the twist rate of the barrel and the velocity of the bullet. My AR15 has a twist rate of 1-in-8 ie for every eight inches the bullet travels down the barrel, the bullet is rotated once. It fires a .223 round at approx 2,800 feet per second so... The formula is (bullet velocity x 720)/twist rate so... (2,800x720)/8 is an incredible 252,000RPM!
When a bullet is fired from a rifle?
When a bullet is fired from a rifle, a chemical reaction in the gunpowder ignites, rapidly expanding gases build up pressure, and the bullet is propelled out of the barrel at high speed. The rifling in the barrel causes the bullet to spin, improving accuracy and stability. Gravity will eventually cause the bullet to drop due to gravity and air resistance.
Does rifling cause the bullet to rise?
It can. The rifling in the barrel causes the bullet to spin. This usually keeps the bullet moving relatively straight (because of gyroscopic stabilisation). However, as the bullet slows down at longer ranges, the spinning can cause it to wobble and drift. This is called spin drift. Spin drift can be upwards, so yes, rifling can cause a bullet to go up, but only at extreme ranges.
