Rifling will leave grooves--impression in a bullet. These grooves can indicate the manufacturer of the gun that fired that bullet, AND, if there is a suspected gun in particular, microscopic variations can be used to confirm or refute that gun's involvement to a high degree of certainty.
The rifling is there to spin the bullet, which gives greater accuracy.
Direction of spin is dependent on the direction of the rifling on the inside bore of the barrel. A bullet will spin the same direction as the rifling.
The stripes of the lands and grooves will be on the sides of the bullet. If the bullet is "stripping" through the rifling of the gun, the striations (proper name for the rifling marks) will be smeared.
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.
the bullet rises because of the rifling in the grooves of the barrel
You compare the rifling marks on the bullet to the rifling in the barrel. You can also compare the firing pin mark on the primer to the firing pin on the gun.
Rifling causes the bullet to spin through the barrel and downrange. This spin stabilizes the bullet, allowing it to maintain a straight course to the target. Without the spin, accuracy would be dismal.
There are spiral grooves engraved on the inside of a rilfe or pistol barrel. When a bullet is fired, it is forced into those grooves, which impart a spin to the bullet. The grooves are called rifling.
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.
The rifling in a firearm is designed to cause the project (bullet) to spin, increase stability and accuracy.
Rifling. The barrel is not smooth on the inside. There are small grooves spiraling down the barrel which makes the bullet spin. Nearly all shotguns do not have rifling in the barrel.
