The short answer is no. You should never attempt to fire any cartridge in a gun other than what it is designed for.
The longer answer is, you may possibly be able to get a .22 cartridge to fire from a 9mm, but it could damage the gun or the person shooting it.
No, the bullet will not seat.
A bullet from a handgun can travel, on average, about a mile.
NO!! Although the bullet diameter is the same, the case length is different and should not chamber in the 380 caliber handgun.
Not reliably. The 9mm bullet is a bit smaller in diameter than a .38, and the cartridge has no rim- it will push into the cylinder. Brass is also likely to split if it DOES fire.
The .22 bullet is smaller than the 9mm in size, (about 6mm) and is lighter in weight.
9mm and 380 both use bullets with a diameter of .355. But the answer to the question you're probably asking is, no, you cannot fire a 9mm parabellum cartridge from a .380 handgun. The 9mm cartridge is different than the .380 cartridge. Even though both are 9mm in diameter, the overall cartridge lengths are different.
No
9 millimeter is the caliber. IMPROVING ANSWER: A "9mm" bullet is actually .355 or .356 of an inch in diameter. So the caliber is about .36, but nobody calls it that because it would be confusing. Everybody calls it a 9mm and if somebody asks you what "caliber" that pistol is, you can answer "It's a 9mm" without having to add or explain anything. further improve: 9mm is the correct answer. you can find the caliber by measuring the diameter of the bullet. translate to millimeters or inches and that's the caliber. 9mm is a 9mm caliber not "around .36"
Generally speaking, the .45 caliber bullet is larger in diameter and heavier than a 9mm bullet.
Caliber refers to the diameter of the bullet the gun fires. The caliber of a 9mm is 9 millimeters. That is about .356 inches.
A base example is: a 9mm parabellum bullet is .356 caliber.
Roughly .35--.36 caliber.
