It depends on several factors, but "about a mile" is a good average.
If you fire a .45 caliber bullet at a paper target, it will leave a .45 inch hole.
this is very controversial subject my father believes a 9mm is a great defense weapon. the problem i have with this caliber is that it velocity is to fast, this means the bullet has the opportunity to travel straight through the target and hit what ever is behind the target. a 45 is slower and heavier bullet. this means that when the bullet hits the target, it delivering all of its kinetic energy when it hits the target. Allowing the shooter to use one bullet rather than 2 or 3 bullets from the 9mm The 9 mm is good for killing from a long distance, but yea if your getting attacked an you shoot the attacker it will take him down.
It disrupts the integrity of what it hits.
The projectile is called a bullet.
It all depends on the hit. Some hits, it can. Others, it won't.
The velocity of a bullet is dependent on many factors. The amount and type of propellant affect velocity, as does the barrel length. The Springfield 30-06 with a 180 grain bullet can have a velocity of 820 meters per second based on a 60 centimeter barrel - again dependent on powder charge and type.
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.
When the bullet penetrates into an object its velocity decreases very much or becomes 0 suddenly. This causes a change a momentum of bullet and impulse is applied. Technically the kinetic energy is converted to potential as a deformation occurs inside that object, transferring some of the kinetic energy into the object.
A bullet from a 9mm pistol generally has the range of 2500yds, but rarely travels that far because before it can it generaly hits something. So in other words with a open range it can travel a little over a mile.
It isn't.Gravity is always acting on the bullet, from the time it rests on the breech to the time it hits target, and every point in between.At the beginning of its motion, the bullet has velocity in a particular direction. Gravity accelerates the bullet 'downwards' and alters the velocity at each point in time and space. Eventually, the combination of the previous motion and the present velocity makes it strike a target, at which point forces in the target and bullet result in all motion ceasing, and these forces become balanced.
I havenever heard of a .54 cal but no, a bullet that will not stay in place for the striking pin will not fire, DO NOT TRY IT, if by some off chance that the striking pin hits the firing cap then the bullet has already started its trajectory at an angle and will probably damage the gun and yourself, it will be hard to find but you may be able to find a a saboe for that caliber, but you may just want to go buy some .54 cal ammo...
Shotguns, using "clay pigeons" used in skeet and trap- to teach the concept of "leading" a moving target. Belt fed .30 caliber machine guns, using a frangible, nonmetalic bullet- used to fire at an armored fighter that had devices to sense and record hits. .50 caliber Browning machine guns- the standard WW 2 gun of a US bomber gunner.
