What is the diameter of a 9 MM bullet?

As far as diameter, there is very little difference. A .357 is .358 in diameter and a 9mm is .356 in diameter.

Yes. .38 special is a revolver cartridge and .380 is an auto cartridge. Also, the .38 will almost always have a heavier bullet and more muzzle energy than a .380. The .38 bullet is 0.357 inches in diameter while the .380 is 0.355 inches in diameter. Technically, the .380 cartridge is considered part of the 9 mm class of bullets. [9 mm x 19 mm = 9 mm Luger or 9 mm Parabellum, 9 mm x 18 mm = 9 mm Tokarov, and 9 mm x 17 mm = .380 ACP]

A 9mm pistol is a pistol that fires a bullet which is 9 MMs in diameter.

Yes they is a differnent. When people say "38" they usually mean .38 special, which is a revolver cartridge. .380 ACP is a semi-automatic cartridge. The bullet in a .380 cartridge, even though it's called .380, is actually very slightly smaller in diameter, and lighter than the bullet in a .38 cartridge. The .38 bullet is 0.357 inches in diameter while the .380 is 0.350 inches in diameter. Technically, the .380 cartridge is considered part of the 9 mm class of bullets. [9 mm x 19 mm = 9 mm Luger or 9 mm Parabellum, 9 mm x 18 mm = 9 mm Tokarov, and 9 mm x 17 mm = .380 ACP]

Yes, the calibre refers to the diameter of the bullet. Therefore, a 9mm would be smaller than a 10 mm.

11.5 mm bullet diameter

A bullet with a diameter of approximately 9mm. Not all 9mm projectiles are exactly 9mm in diameter - the 9x19 Parabellum/Luger has a diameter of 9mm, while the 9x18 Makarov has a diameter of 9.27mm, the 9x23 Steyr has a diameter of 9.03mm, etc.

It depends on the bullet. A 7.62 round is 7.62 mm in diameter, and a 303 is 0.303 inch in diameter and a 22 bullet is 0.22 inch diameter.

The .9x17 (.380 ACP) is a cartridge designed to be used in compact, unlocked breech pistols. The .38 Special is a rimmed cartridge designed for use in revolvers, while the .38 Super is an automatic pistol cartridge, with much too high a chamber pressure to be used in an unlocked breech weapon. The .380 has a bullet diameter of .355 inches, pushing projectiles ranging from 85 - 100 grains. The .38 Super also has a bullet diameter of .355 inches, but pushes a projectile ranging from 90 - 150 grains. The .38 Special has a bullet diameter of .357 inches, and uses a projectile ranging from 100 - 160 grains. The .38 bullet is 0.357 inches in diameter while the .380 is 0.355 inches in diameter. Technically, the .380 cartridge is considered part of the 9 mm class of bullets. [9 mm x 19 mm = 9 mm Luger or 9 mm Parabellum, 9 mm x 18 mm = 9 mm Tokarov, and 9 mm x 17 mm = .380 ACP]

It depends on the bullet weights. The 9 mm (AKA 9x19 mm, 9 mm Luger, or 9 mm Parabellum) is faster than the .380 ACP (AKA 9 mm Kurz) except when you compare the lightest .380 bullets to the heaviest 9 mm bullets. If you compare the same bullet weights in each, the 9 mm is always faster.

If you are talking about a .45 acp The bullet diameter of .451 equates to 11.5mm. If you are talking about a bullet used in rifle calibers (45-70) etc.then the bullet diameter of .457 equates to 11.7mm.

I think you mean .32 caliber, not mm. It means that the gun fires a bullet that is about 32/100ths of an inch in diameter. A 9mm fires a bullet 9mm in diameter- or about .35 inches in diameter. A 32 mm bullet would be about the size of big (D cell) flashlight battery!

If you mean the 9 mm Parabellum AKA 9x19 mm or 9 mm "Luger", the .38 Special is physically larger. The case length of the .38 is 0.401 inches longer. The over all loaded cartidge length of the .38 is 0.381 inches longer. Case diameter is nearly identical between the two, but the .38 has a larger rim/case head by 0.046 inches. The 9 mm fires a 0.355 inch diameter bullet whereas the .38 fires a 0.357 inch diameter bullet.

Millimeters, it is the size of the bullet.

none, they are the same caliber. Answer: There are several ddifferences, A comparison of the data is given below: Luger Case type Rimless Bullet diameter 7.85 mm (0.309 in) Neck diameter 8.43 mm (0.332 in) Base diameter 9.93 mm (0.391 in) Rim diameter 9.98 mm (0.393 in) Case length 21.59 mm (0.850 in) Overall length 29.85 mm (1.175 in) Browning: Case type Semi-rimmed, straight Bullet diameter 7.8 mm (.309 in) Neck diameter 8.5 mm (.336 in) Base diameter 8.6 mm (.337 in) Rim diameter 9.1 mm (.358 in) Case length 17.3 mm (.680 in) Overall length 25.0 mm (.984 in)

The caliber of a bullet, refers to it's diameter in inches. But sometimes other measurements are used, such as mm.

Both terms describe the diameter of the bullet in decimal parts of an inch. For example, a .357 bullet is 357 thousands of an inch in diameter and the .45 bullet is 45 hundredths of an inch in diameter. These labels of bullets are most common in the United States. Much of the world refers to bullet sizes in metric terms, i.e. 9mm means a bullet that is 9 millimeters in diameter.

9mm means the firearm shoots a bullet that is about 9 millimeters wide.

They are different ways of expressing the same thing. A bullet that is 7.65mm is just that- 7.65 millimeters in diameter. Is the US, we frequently use caliber rather than millimeters- that same bullet was be a .32 caliber- or 32/100ths of an inch in diameter.

196 grains refers to weight. In this case, the weight of a bullet. 7.62mm is the diameter of the bullet. This is most likely a 7.62x54R cartridge.

circumference = diameter X pi diameter = circumference/pi diameter = 55 mm/3.1416 diameter = 17.5 mm

Area = pi*4.52 = 63.617 square mm to 3 dp.

There is no 32mm handgun. That would fire a bullet more than an inch in diameter.

Caliber means the diameter of the bullet. A .40 caliber cartridge has a bullet that is .40 inches in diameter. A 9mm cartridge has a bullet that is 9 millimeters in diameter. Yup...reminds me of Joe the Human Cannonball at the circus...Poor Joe died but they couldn't find a replacement of his caliber.
