It depends on several factors, but it ranges from about 830 feet per second to about 1180 FPS.
A 9 mm round out of a Glock 17 is 1148 feet per second
This is the approximate size of a .45 caliber round, the conversion being .443 inches.
7.62 caliber
No. The AK-47 fires the 7.62x39mm round, which is of the .30 caliber, smaller than the .45 caliber.
Assuming the question is in regard to firearms and ammunition, you can read the "caliber" of a round as a decimal how wide the bullet is in inches. So a .40 caliber round is .4 inches wide, or about 10.16 millimeters wide. A .45 caliber round would be .45", so a little bit fatter than the .40 caliber round. The caliber doesn't tell the whole story of a round though, it doesn't say how long the bullet is, how heavy, how big the casing behind the round is, how much kinetic energy is hits with, etc. The .40 S&W round has an average of 425 ft/lbs of energy right at the muzzle, while the .45 ACP, a "bigger" round, has about 400 ft/lbs.
It depends on what you mean. A .22 caliber gun is a gun that will fire a .22 caliber cartridge. If you want an example of a .22 caliber gun, one example would be a Smith and Wesson model 17. this is true but u must remember that when describing a caliber u are talking about the diameter of the round . for example the .22 long rifle is the same diameter as the 5.56 that the m4 shoots . if the round is refer ed to as the .22 it will most likely be rim fire as other .22 like 5.7,5.56,and.223 will be center fire
17 caliber rimfire
The radius of a .68 caliber paintball round is half of its diameter. Since the caliber is given in inches, the radius would be 0.34 inches.
There are several different .17 caliber catridges- some rimfire, some centerfire.
Yes, that is correct.
.4005 inches.
