First, lets go over what happens when a bullet is fired from a firearm. 1) A cartridge (a bullet pressed into a metalic cartidge which contains smokeless gunpowder and a primer) is loaded into the firing chamber of the firearm. 2) When the trigger is pulled, a hammer hits a firing pin which impacts the primer on the cartridge. 3) The primer ignites the smokeless gunpowder in the cartridge which produces a high pressure explosion. 4) This explosion forces the bullet down the barrel of the firearm and toward the target. The barrel of most firearms contains groves which help stabilize the bullet in flight by imparting a spin. These groves leave marks on the bullet itself which can be compared with other bullets fired from the same firearm. In addition, the firing pin on the firearm leaves a "dimple" on the spent primer of the metallic cartridge. This can also be measured and compared to other cartridges from the same firearm.
No. A bullet is traced by examining the markings on the sides of the round that are created as it is pushed out the barrel. Each barrel imprints a unique set of microscopic scratch lines on the bullet's sides; it's like the bullet has it's own finger prints. But you have to have the gun to do this comparison.
Sometimes you can.
A cartridge will ignite if the primer is struck, regardless of whether it is in a gun at the time.
A bullet fired from a gun
The mass of a bullet is nowhere near the mass of a gun. A bullet weighs at most a few hundred grains. Most guns weigh at least a couple of pounds, some weigh several pounds (talking about handguns and rifles).
Rifling marks, the marks etched into a bullet as it travels through a gun's barrel, are to a gun as fingerprints are to a person. To see if a fired round came from a particular gun, the gun is test fired into a pool of water (to stop the bullet without changing its shape) then the marks on the test fired bullet and the bullet in question are compared. Knowing the trajectory of a bullet points you in the direction of its origination. There are also some clues that will help you determine from how far a shot was fired, such as approximate speed on impact and the presence of burnt gunpowder.
Sometimes you can.
the bullet and the barrel of the gun without a bullet it wont do anything by By Ray Lee Charles the top gun industries.
When a bullet is fired from a rifled firearm, the rifling leaves marks on the bullet. Those marks are unique to that gun, and no other gun makes exactly the same marks. If a bullet (or fired cartridge casing) is recovered from a crime scene, and we suspect that YOUR gun was used to commit this crime, then a sample bullet is fired from your gun, and compared to the crime scene bullet. A comparison microscope is used to compare the bullets, or marks made on the fired cartridge case by the extractor and firing pin.
No. Yes. All you have to do is strike the bullet's primer with a sharp corner of the gun.

On the sight of the wound, there may be a scar...
The gun weighs MUCH more than the bullet.
A bullet fired from a gun
If the glass fracture resulted from when a bullet hit the car windshield, police can predict the bullet type and therefore the kind of gun used. If they trace the purchase of that type of gun, this narrows their suspects. they may also be able to say something about a bullet's trajectory, or they may be able to determine from which side the glass was impacted.
Affix the gun to a target. Load the bullet into a cartridge. Load the cartridge into a second gun. Aim carefully, squeeze the trigger. If you have done everything right, you will have shot the gun with a bullet.
It's the recoil from the force of the bullet being fired. The gun powder pushes the bullet forward and also equally pushes the gun back into your hand.
