The diamater of a 9mm parabellum bullet is 9.03 millimeters, or .356 of an inch.
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]
As far as diameter, there is very little difference. A .357 is .358 in diameter and a 9mm is .356 in diameter.
A 9mm pistol is a pistol that fires a bullet which is 9 MMs 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]
The diameter of the bullet casing, measured at 7.3 mm, is 7.3 millimeters.
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 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.
Yes, the calibre refers to the diameter of the bullet. Therefore, a 9mm would be smaller than a 10 mm.
A .222 caliber bullet has a diameter of 5.56mm.
A .38 caliber bullet typically has a diameter of approximately 9.1 millimeters. The designation ".38 caliber" refers to the bullet's diameter, which is often rounded to the nearest hundredth of an inch. Therefore, a .38 caliber bullet can be generally considered to be around 9 mm in metric measurements.
