The diameter of a 9mm round is 9 millimeters, which is approximately 0.354 inches. This measurement refers to the bullet's diameter, commonly associated with the 9mm Parabellum cartridge. The "9mm" designation indicates that the bullet has a nominal diameter of 9mm.
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.
They use bullets of the same diameter, but with different weight ranges, which happen to overlap. The .380 uses a 9mm diameter bullet in a 17mm long case. The 9mm uses a 9mm diameter bullet in a 19mm long case.
The 9mm round in loaded with a bullet diameter of .356"in.
Bullet diameter of a 9mm is .355; for a 38 it is .357. 38 case is longer. Additionally, a 9mm is designed to be used in a semi-automatic pistol, and a .38 is designed to be used in a revolver, although, there are a couple of revolvers that will chamber 9mm.
A 9mm circle can be represented by the diameter of a standard 9mm bullet, which is commonly used in handguns. This diameter is often associated with ammunition such as the 9mm Parabellum, widely used in both military and civilian contexts. Additionally, a 9mm circle can be visualized as the size of a small coin, like a dime, which measures approximately 17.91mm in diameter, making a 9mm circle roughly half that size.
9mm
380 and 9mm projectiles are .355 in diameter _________________________ Most of the time, when people use the term 9mm, they are referring to a 9mm parabellum. A 9mm parabellum cannot be fired from a .380. The 9mm cartridge is longer. _________________________ The BULLET is the part of the cartridge that is the projectile. While 9mm parabellum and .380 ACP use the same diameter bullets, the CARTRIDGES are not interchangeable.
Projectile diameter is the same. 9mm case length is longer.
The 9mm means that the bore is 9mm inside diameter . The bullet will be roughly 9mm or a little more in diameter. The 45 means basically the same, the bore of the barrel is .45 caliber. but the bullet will be anywhere from .451 to .452 in diameter depending on manufacture and on type of metal the bullet is made out of. So basically yes.
The diameter of the bullets
The main difference between a 9mm and a .45 caliber bullet is the diameter. A 9mm bullet has a diameter of 9 millimeters, while a .45 caliber bullet has a diameter of .45 inches. The .45 caliber bullet is larger and generally heavier than the 9mm bullet, resulting in differences in recoil, speed, and stopping power.
Diameter = 2 x radius = 18 mm .
