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.
The most obvious different is the 10mm bullet is smaller in diameter than the .45. A 10mm bullet is .40 of an inch and the .45 is .45 of an inch. Other differences, depending on exactly which cartridge you are referring to, are muzzle energy and velocity.
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.
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.
The maximum effective range of a .45 caliber bullet is approximately 120 meters.
NO!!! DO NOT ATTEMPT THIS!!!
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.
