At the instant the gun fires, the bullet is at rest- speed zero. As the expanding gasses from the burning gunpowder reach the bullet, they begin pushing the bullet up the barrel. It's speed is increasing- and the longer the push, the higher the speed. There IS a point of diminishing returns- where a barrel LONGER than the perfect length begins to slow the bullet- you have used all the expanding gasses, and now friction is slowing the bullet. If you had a barrel 20 ft long, the bullet would not make it all the way up the barrel, it would stop.
For barrels on any realistically-usable weapon, a longer barrel will provide more momentum to the bullet than a shorter one. In addition, longer rifled barrels will also impart more spin, which will increase accuracy.
What else can I help you with?
How far will a bullet travel when fired without a gun?
Not very far - several feet, perhaps, depending on a few things like caliber and what sets it off. The nature of Physics dictates that the lighter component will be launched. Generally the case (brass) is the part that is lighter. Smokeless powder burns, it does not explode. The burning of the powder in a restricted space (the chamber/barrel of a gun) enables pressures to rise and propel the bullet as significant velocity. Outside of these confines, the powder is not able to develop significant pressure. The inertia of the heavier component (often times the bullet) causes it to move very little. The lighter component will be launched but at a significantly reuced velocity from that which the gun barrel will propel the bullet. I have seen ammunition that "cooked off" in a fire. Generally the bullet is still in the case (brass) but the primer is the part that was propelled.
Does a bullet shot from a gun undergo any acceleration after it leaves the barrel?
No- or minimal at best. Acceleration of the bullet comes from gas expanding inside the barrel, pushing the bullet. Once it leaves the barrel, (or within a VERY short distance) gas is no longer pushing, and acceleration stops, and bullet begins to slow from air resistance.
How does a 22 caliber bullet act in the air?
Assuming the bullet is fired from a gun, the bullet will move out of the bore with a high velocity and will immediately begin falling and decelerating. If the bore is rifled, the bullet will also rotate on its long axis (providing stability in flight).
When a rifle is fired at a distant target the barrel is not lined up exactly on the target so why is it not lined up exactly on the target?
The instant the bullet leaves the barrel it is subject to gravity. If the barrel is lined up exactly on a distant target, the bullet will fall short. The longer the distance, the more elevation is required. The same applies to a football, baseball, or basketball. When the person you are throwing it to is far away, you throw it higher so that it will reach them. With a bullet the principle is the same. You must also allow for wind
How do you decrease momentum over a short period of time?
To decrease momentum over a short period of time, you can apply an external force in the direction opposite to the momentum. This force can be applied through friction, air resistance, or another external mechanism to slow down the object or change its direction quickly. Alternatively, you can transfer momentum to another object in the opposite direction through a collision or interaction.
Does a bullet of the same caliber travel faster if fired through a rifle rather than a pistol?
a bullet of the same caliber and same grains of powder fired from a long barrel will have a higher muzzle velocity than if fired from a short barrel.
What is a squib fire of a shotgun?
When the short & wad do not exit the barrel when fired, you have a squib fire, on any gun.
How does rifle barrel length affect bullet performance?
Doesnt. Twist and bullet weight will decide much of the accuracy. Long barrel for magnums because of the amount of powder being burned is important. Otherwise short barrel in any rifle will just increase muzzle flash and report.

What is the maximum range of?
the range of a 9x19mm would be 2500 yards but with such a short barrel, slow bullet speed and others, the chances of accurate hits is 0%
Is there a way to find exactly which gun fired the bullet if there are several guns and several bullets?
Yes, there is. Each gun leaves different marks on the bullet as it travels down the barrel. It is just a question of test firing each of the guns available into water. Water stops the bullet in a very short distance without deforming the bullet. Then the sample bullet from the water is placed on one side of a comparison microscope and one of the bullets in question is placed on the other side of the microscope. By careful manipulation of the bullets it's possible to look at both of them to see if they match. If they do, question answered. If they don't, check the sample from the water against one of the other unknown bullets. This process is repeated using test bullets from each of the guns and comparing them against all the unknown bullets. Eventually it is possible to tell which weapon fired which bullet(if all the guns that were fired are available for test firing). The process will also tell whether all the weapons fired are accounted for. If there are bullets that don't match any of the test fired bullets then one, or more, gun/s must be missing

When was Nothing Short of a Bullet created?
Nothing Short of a Bullet was created in 2001.
What is the maximum range of the 9mm?
