Depends on which .45- 45 Colt, 45 ACP, 45 Magnum, 45-70, and which bullet, and what it is fired from. If you mean the .45 ACP fired by a 1911A1 pistol, velocity varies from 830 FPS up to about 1020 fps. Slow, fat, but gets the job done.
The .45 caliber bullet is not used in a sniper rifle.
The most basic answer is, a 9mm has a smaller diameter. Other differences, (in most cases) less muzzle energy, smaller and lighter bullet, higher velocity.
Approximately 900feet per second depending on the bullet (155grn or 225grn?).
If you mean "farther" yes, generally speaking, a .22 will travel further than a .45. The .45 is a much heavier bullet and loses velocity at a faster rate.
45 ACP (auto) has a muzzle velocity of anywhere from 830-1100 fps, depending on the load. There ARE other .45 cartridges.
Between 830 and 1300 feet per second, depending on the load and the barrel length.
Noop. an M16 fires a 5.56mm (or .223 caliber) bullet. A .45 caliber shoots a bullet that is ~11.43mm.
The main difference between a 9mm and a .45 caliber bullet is the diameter. A 9mm bullet has a diameter of 9 millimeters, while a .45 caliber bullet has a diameter of .45 inches. The .45 caliber bullet is larger and generally heavier than the 9mm bullet, resulting in differences in recoil, speed, and stopping power.
The maximum effective range of a .45 caliber bullet is approximately 120 meters.
NO!!! DO NOT ATTEMPT THIS!!!
If you mean the .45 ACP (.45 Auto) the velocity at the muzzle depends on the load of the particular cartridge. Typically somewhere between 830 and 1080 feet per second.
Yes, a 45 caliber bullet is bigger than a 40 caliber bullet. A .45 is0.45 inches wide in diameter and a .40 is 0.4 inches in diameter.
